  • How do I set up an email server that automatically maintains a list of previous recipients?

    - by hsivonen
    I want to set up an email server with the following characteristics. What software (besides bogofilter and clamav that I'm naming) should I use and what HOWTOs should I read? The server should run some flavor of Linux that's as low-maintenance as possible and self-updates for security patches in a timely fashion. (Debian stable?) When email is sent, all the recipients are stored in the list of previous recipients maintained by the server. Scan incoming messages with clamav and treat as spam if it contains viruses. When email arrives (if it passed clamav), if the sender is on the list of previous recipients, bypass spam filter. If the List-Id header names a mailing list on a manually maintained list of known-clean mailing lists, bypass spam filter and deliver into a mailbox depending on the mailing list name. Email that wasn't from previous recipients, manually white listed domains or mailing lists gets filtered by bogofilter. Spam goes into a spam mailbox. Email considered to be ham should automatically be fed to bogofilter training as ham. Email considered to be spam (incl. messages with viruses) should be automatically fed to bogofilter training as spam. There should be mailboxes for false ham and false spam that an IMAP client can move email into so that the server retrains bogofilter appropriately. Email sending requires SMTP over SSL. Email reading requires IMAPS. Should I also want to use SpamAssassin in addition to bogofilter?

  • How can people still be getting spam from a hotmail account that's been closed?

    - by Marplesoft
    My wife had an old hotmail account which she recently closed. Some people that she used to communicate with from that account have recently been receiving spam emails from this account. I don't see how this is possible because the account is closed. I considered that maybe the email address is being spoofed, is there a way I can tell from looking at the email headers or something? Or should I take this up with hotmail?

  • Why some "non-profit" hoax and spam are created? [closed]

    - by naxa
    Many spam/hoax has no direct link to any ripoff site or similar, they're just making sure people spread them ("forward this to at least 10 people or else"). Some of those may be created out of good faith, I'm not interested in those... But the rest, I since long suspect that there is some other reason for making them other than making fun of people (without getting much of the feedback)... Why are these created?

  • phpBB - Reducing Spam

    - by user44175
    I've installed phpBB Forums last week and the past 2 days I've been getting users sign up and posting spam chinese emails on each topic. I have:- Added captcha on registration Made sure users have to verify subscription by email before allowing to post What else can I do to stop this from happening? I've banned their IP addresses but this doesn't stop them from using a proxy to keep spamming the forums. I've read I can block all chinese IP addresses through ACP but is this the best step to block all this? Seems to be all chinese spam at the minute, any help would be much appreciated.

  • How can I reduce the number of spammers registering with my phpBB site?

    - by Jayapal Chandran
    I have a site which runs phpBB, on this site I have enabled user authentication through email when registering enabled captcha However I still get spam users every 20 to 30 minutes. Is there anything I can do to prevent this with the ucp.php file? I have already loaded a large list of IP addresses yet there are spam users registering all the time. One thing I can do is I can check the bounce mail to find the username and can pipe bounced mails to a php script and immediately delete that user, but I have not got any bounce back from hotmail or some other email clients. So this way it will catch hold of a certain percent of spam users but there are still a huge amount of users spamming. What else can I do to prevent spammers abusing my phpBB site?

  • How to test email spam scores with amavis?

    - by CaptSaltyJack
    I'd like a way to test a spam message to see its spam scores that SpamAssassin gives it. The SA db files (bayes_toks, etc) reside in /var/lib/amavis/.spamassassin. I've been testing emails by doing this: sudo su amavis -c 'spamassassin -t msgfile' Though this yields some strange results, such as: Content analysis details: (3.7 points, 5.0 required) pts rule name description ---- ---------------------- -------------------------------------------------- 3.5 BAYES_99 BODY: Bayes spam probability is 99 to 100% [score: 1.0000] -0.0 NO_RELAYS Informational: message was not relayed via SMTP 0.0 LONG_TERM_PRICE BODY: LONG_TERM_PRICE 0.2 BAYES_999 BODY: Bayes spam probability is 99.9 to 100% [score: 1.0000] -0.0 NO_RECEIVED Informational: message has no Received headers 0.2 is an awfully low scores for BAYES_999! But this is the first time I've used amavis, previously I've always just used spamassassin directly as a content filter in postfix, but apparently running amavis/spamassassin is more efficient. So, with amavis in the picture, how can I run a test on a message to see its spam score breakdown? Another email I ran a test on got this result: 2.0 BAYES_80 BODY: Bayes spam probability is 80 to 95% [score: 0.8487] Doesn't make sense, that BAYES_80 can yield a higher score than BAYES_999. Help!

  • Server being used to send spam mail. How do I investigate?

    - by split_account
    Problem I think my server is being used to send spam with sendmail, I'm getting a lot of mail being queued up that I don't recognize and my mail.log and syslog are getting huge. I've shutdown sendmail, so none of it is getting out but I can't work out where it's coming from. Investigation so far: I've tried the solution in the blog post below and also shown in this thread. It's meant to add a header from wherever the mail is being added and log all all mail to file, so I changed the following lines in my php.ini file: mail.add_x_header = On mail.log = /var/log/phpmail.log But nothing is appearing in the phpmail.log. I used the command here to investigate cron jobs for all users, but nothing is out of place. The only cron being run is the cron for the website. And then I brought up all php files which had been modified in the last 30 days but none of them look suspicious. What else can I do to find where this is coming from? Mail.log reports Turned sendmail back on for second. Here is a small sample of the reports: Jun 10 14:40:30 ubuntu12 sm-mta[13684]: s5ADeQdp013684: from=<>, size=2431, class=0, nrcpts=1, msgid=<[email protected]>, proto=ESMTP, daemon=MTA-v4, relay=localhost [127.0.0.1] Jun 10 14:40:30 ubuntu12 sm-msp-queue[13674]: s5ACK1cC011438: to=www-data, delay=01:20:14, xdelay=00:00:00, mailer=relay, pri=571670, relay=[127.0.0.1] [127.0.0.1], dsn=2.0.0, stat=Sent (s5ADeQdp013684 Message accepted for delivery) Jun 10 14:40:30 ubuntu12 sm-mta[13719]: s5ADeQdp013684: to=<[email protected]>, delay=00:00:00, xdelay=00:00:00, mailer=local, pri=32683, dsn=2.0.0, stat=Sent Jun 10 14:40:30 ubuntu12 sm-mta[13684]: s5ADeQdr013684: from=<[email protected]>, size=677, class=0, nrcpts=1, msgid=<[email protected]>, proto=ESMTP, daemon=MTA-v4, relay=localhost [127.0.0.1] Jun 10 14:40:31 ubuntu12 sm-msp-queue[13674]: s5AC0gpi011125: to=www-data, ctladdr=www-data (33/33), delay=01:39:49, xdelay=00:00:01, mailer=relay, pri=660349, relay=[127.0.0.1] [127.0.0.1], dsn=2.0.0, stat=Sent (s5ADeQdr013684 Message accepted for delivery) Jun 10 14:40:31 ubuntu12 sm-mta[13721]: s5ADeQdr013684: to=<[email protected]>, ctladdr=<[email protected]> (33/33), delay=00:00:01, xdelay=00:00:00, mailer=local, pri=30946, dsn=2.0.0, stat=Sent Jun 10 14:40:31 ubuntu12 sm-mta[13684]: s5ADeQdt013684: from=<[email protected]>, size=677, class=0, nrcpts=1, msgid=<[email protected]>, proto=ESMTP, daemon=MTA-v4, relay=localhost [127.0.0.1] Jun 10 14:40:31 ubuntu12 sm-msp-queue[13674]: s5ACF2Nq011240: to=www-data, ctladdr=www-data (33/33), delay=01:25:29, xdelay=00:00:00, mailer=relay, pri=660349, relay=[127.0.0.1] [127.0.0.1], dsn=2.0.0, stat=Sent (s5ADeQdt013684 Message accepted for delivery) Jun 10 14:40:31 ubuntu12 sm-mta[13723]: s5ADeQdt013684: to=<[email protected]>, ctladdr=<[email protected]> (33/33), delay=00:00:00, xdelay=00:00:00, mailer=local, pri=30946, dsn=2.0.0, stat=Sent Ju Further Investigation Spotted 4 spam accounts registered in the past day, which is suspicious however all have normal user privileges. There are no contact forms on the site, there are a number of forms and they take either filtered text input or plain text input. Mail is still being queued up having switched the website to maintenance mode, which blocks out everyone but the admin. Ok more investigation, it looks like the email is being send by my websites cron which runs every 5 minutes. However there are no cron jobs I've set-up which run more than once an hour and show on the website log so presumably someone has managed to edit my cron somehow.

  • In Exim, is RBL spam rejected prior to being scanned by SpamAssassin?

    - by user955664
    I've recently been battling spam issues on our mail server. One account in particular was getting hammered with incoming spam. SpamAssassin's memory use is one of our concerns. What I've done is enable RBLs in Exim. I now see many rejection notices in the Exim log based on the various RBLs, which is good. However, when I run Eximstats, the numbers seem to be the same as they were prior to the enabling of the RBLs. I am assuming because the email is still logged in some way prior to the rejection. Is that what's happening, or am I missing something else? Does anyone know if these emails are rejected prior to being processed by SpamAssassin? Or does anyone know how I'd be able to find out? Is there a standard way to generate SpamAssassin stats, similar to Eximstats, so that I could compare the numbers? Thank you for your time and any advice. Edit: Here is the ACL section of my Exim configuration file ###################################################################### # ACLs # ###################################################################### begin acl # ACL that is used after the RCPT command check_recipient: # to block certain wellknown exploits, Deny for local domains if # local parts begin with a dot or contain @ % ! / | deny domains = +local_domains local_parts = ^[.] : ^.*[@%!/|] # to restrict port 587 to authenticated users only # see also daemon_smtp_ports above accept hosts = +auth_relay_hosts condition = ${if eq {$interface_port}{587} {yes}{no}} endpass message = relay not permitted, authentication required authenticated = * # allow local users to send outgoing messages using slashes # and vertical bars in their local parts. # Block outgoing local parts that begin with a dot, slash, or vertical # bar but allows them within the local part. # The sequence \..\ is barred.

  • Using my own Postfix, filtering spam and getting all the mail into my ISP's inbox

    - by djechelon
    Hello, I currently own a domain bought via GoDaddy.com, which provides me a basic email setup for the most common needs. I configured it to forward all mail to [email protected] to [email protected]. I also own a virtual server with a running Postfix that I use for a specific website (all mail to somedomain.com gets forwarded via LMTP to a program written by me). Since I'm recently experiencing some harassing by spammers, since GoDaddy doesn't seem to filter spam, and since my Windows Phone's Pocket Outlook cannot filter spam, I would like to use SpamAssassin to filter inbound spam by changing my domain's MX records to my server My ideal setup is the following: All mail delivered to somedomain.com gets redirected via LMTP as usual via virtual transport without any spam check All mail to [email protected] gets redirected to [email protected] after a severe spam check I don't care about [email protected] since I use just one address for now I would like to train SpamAssassin with customized spam rules, possibly based on the presence of certain keywords (links to certain unsubscribe pages I found recurring) I currently configured Postfix with transport somedomain.com lmtp:[127.0.0.1]:8025 .somedomain.com error: Cannot accept mail for this domain relay somedomain.com OK (I guess I should add mydomain.com OK too) virtual @mydomain.com [email protected] (looks like a catch-all rule, it's OK as requirement 3) I installed SpamAssassin, I can do rcspamd start and set it to boot with the server, but I don't know if there is anything else to do for use in Postfix, and how to apply requirement 1 (only mail to mydomain.com gets filtered) I also tried to send an email via Telnet to make sure my settings are ready for MX change. I received the message into my account but I found that it gone through secureserver.net, like Postfix didn't rewrite the destination but simply relayed the message. Thank you in advance. I'm no expert in SpamAssassin, and I have little experience in Postfix (enough to avoid making my server an open relay)

  • What Kind of Spam is This? Testing Blog Comment Limits

    - by Yar
    I received this comment on one of my blogs today (on blogger.com): Easily I agree but I about the post should acquire more info then it has. It's the third in a series. Before there was: I will not acquiesce in on it. I over precise post. Expressly the title attracted me to be familiar with the sound story. and before that Your blog keeps getting better and better! Your older articles are not as good as newer ones you have a lot more creativity and originality now keep it up! It is obviously computer-generated (well, not this last one). The comments are from Anonymous, so they're not trying to legitimate a user on Blogger. Is this a spam attack? What might its goal be? Or are they just testing my blog to see if I reject or not? Does this kind of "attack" have a name?

  • How to send emails without getting into Spam Act trouble?

    - by Jason
    Lets say I have a database of 60,000 emails. I would like to send them an email notifying them of a new related service (similar to what they've signed up) which adds value to what they already signed up to. I know most of them would welcome it but they did not opt-in for this new related service. I don't want to send out the email invite only to find out I got into some Spam Act trouble. What is a friendly way to reach these targetted audience?

  • How do you make sure email you send programmatically is not automatically marked as spam?

    - by Leon Bambrick
    This is a tricky one - and I've always relied on techniques such as permission-based emails (i.e. only sending to people you have permission to send to) and not using blatantly spamish terminology. Of late, some of the emails I send out programmatically have started being shuffled into people's spam folder automatically - and I'm wondering what i can do about it. This is despite the fact that these particular emails are not ones that humans would mark as spam (specifically, they are emails that contain license keys that people have paid good money for, so I don't think they're going to consider them spam) I figure this is a big topic in which I am essentially an ignorant simpleton.

  • Why is my Drupal Registration email considered spam by gmail? (headers included)

    I just created a Drupal website on a uni.cc subdomain that is brand-new also (it has barely had the 24 hours to propagate).

  • Comparison of Firewall, Intrusion Prevention, Detection and Antivirus Technologies in Organizational

    - by Berkay
    in these days i'm reading about intrusion prevention/detection systems.When reading i really confused in some points. First, the firewall and antivirus technologies are known terms for years, however now IDS becomes popular. My question includes: in organizational network architectures when/where do we use these systems ? What are the benefits of using each ? Does Firewall contains all these others? If you give me some examples, it will help much. Thanks.

  • dlink arp spoofing prevention

    - by Wiploo
    someone can help me understanding arp spoofing prevention on dlink dgs-3100 (ftp://ftp2.dlink.com/PRODUCTS/DGS-3100-48P/REVA/DGS-3100-48P_MANUAL_3.60_EN.PDF). I'd like to protect my gateway MAC/IP from spoofing so I'have tryed to add a rule "IP: 192.168.1.1 MAC: aa-aa-aa-aa-aa-aa" flagging all the port of the switch as untrusted. When I apply the rule I lose connection to all pc attached to the switch. I certanly made some errors, but I can't understand what is wrong. Best Regards

  • Why are emails sent from my applications being marked as spam?

    - by Brian
    Hi. I have 2 web apps running on the same server. The first is www.nimikri.com and the other is www.hourjar.com. Both apps share the same IP address (75.127.100.175). My server is through a shared hosting company. I've been testing my apps, and at first all my emails were being delivered to me just fine. Then a few days ago every email from both apps got dumped into my spam box (in gmail and google apps). So far the apps have just been sending emails to me and nobody else, so I know people aren't manually flagging them as spam. I did a reverse DNS lookup for my IP and the results I got were these: 100.127.75.in-addr.arpa NS DNS2.GNAX.NET. 100.127.75.in-addr.arpa NS DNS1.GNAX.NET. Should the reverse DNS lookup point to nimikri.com and hourjar.com, or are they set up fine the way they are? I noticed in the email header these 2 lines: Received: from nimikri.nimikri.com From: Hour Jar <[email protected]> Would the different domain names be causing gmail to think this is spam? Here is the header from one of the emails. Please let me know if any of this looks like a red flag for spam. Thanks.

  • Exchange 2003 mail non-delivery (NDR), spam activity? events 7002 & 7004

    - by HighTechGeek
    Windows Server 2003 Small Business Server SP2 Exchange Version 6.5 (Build 7638.2: Service Pack 2) This network has been neglected and has been having email problems for years and was on many blacklists. I was called in after the server eventually crashed... I got the server back up and running, but email problems persist. Outgoing mail delivery is sporadic. Sometimes the mail goes through, sometimes a delayed delivery report is generated after a day or more, and sometimes it seems to go through, but the recipient never receives it. Not sure if spammers are successfully using the server as a relay (see event entries below after turning on maximum SMTP logging)... User PCs infected with viruses and server was blacklisted on many sites (I used mxtoolbox.com) I have cleaned all the PCs and changed all passwords (including administrator) I have requested removal from all of the blacklists - most have removed the listing, some take more time. I have setup rDNS pointer records with the ISP (Comcast) - that was one reason for some of the blacklistings. I have tested that it's not an open relay using telnet as described here: www.amset.info/exchange/smtp-openrelay.asp I followed the advise of a Spamhaus & Microsoft article to enable maximum SMTP logging. http://www.spamhaus.org/faq/answers.lasso?section=isp%20spam%20issues#320 which directed me to Microsoft KB article 895853, specifically, the part 2/3 down titled: "If mail relay occurs from an account on an Exchange computer that is not configured as an open relay" . The Application Event Log is filling with this type of activity (Event ID 7002, 7002 & 3018 errors): Event Type: Error Event Source: MSExchangeTransport Event Category: SMTP Protocol Event ID: 7004 Date: 1/18/2011 Time: 7:33:29 AM User: N/A Computer: SERVER Description: This is an SMTP protocol error log for virtual server ID 1, connection #621.
