  • How to generate new CSRs for TLS use in sendmail?

    - by Mikey B
    SendMail 8.13.8 | CentOS 5.x Hi Guys, I'm using ca-signed TLS certificates on my sendmail server and they are up for renewal soon. Our new CA doesn't like our old CSR so I need to generate a new CSR. Can someone point me to the procedure for doing this (without affecting the production certs that are already in use)? I'm paranoid of overwriting the old TLS certs in the process of generating a CSR. Most of the instructions I've found are for implementing self-signed TLS certs -- which isn't an option for me at this time. I'm thinking it would something like: openssl req -new -nodes -out new-tls.csr -keyout new-tls-private.key But I wasn't sure if I was missing some options there such as the -x509 option... -M

    I have about 300 emails (gmail) that go like this: Dear [name] Order ID:123456789 Purchased by: [name I need] (blah blah another 26 lines of crap (total of 30 lines)) What I need help is how to save gmail's mails locally into .txt and how to export 4th line from each text file.

  • Distro List - can a member be blind copied?

    - by Jessie
    Is it possible to set up a distro list on an exchange server to send a blind copy to one of the recipients? For example: I'd like to have a distro go to Help, Support, and IT. However, I don't want the sender to know it goes to Help if they expand the distro in the To: field. I know this is most likely impossible, but I figured it wouldn't hurt to ask.

  • Ubuntu Launcher Items Don't Have Correct Environment Vars under NX

    - by ivarley
    I've got an environment variable issue I'm having trouble resolving. I'm running Ubuntu (Karmic, 9.10) and coming in via NX (NoMachine) on a Mac. I've added several environment variables in my .bashrc file, e.g.: export JAVA_HOME=$HOME/dev/tools/Linux/jdk/jdk1.6.0_16/ Sitting at the machine, this environment variable is available on the command line, as well as for apps I launch from the Main Menu. Coming in over NX, however, the environment variable shows up correctly on the command line, but NOT when I launch things via the launcher. As an example, I created a simple shell script called testpath in my home folder: #!/bin/sh echo $PATH && sleep 5 quit I gave it execute privileges: chmod +x testpath And then I created a launcher item in my Main Menu that simply runs: ./testpath When I'm sitting at the computer, this launcher runs and shows all the stuff I put into the $PATH variable in my .bashrc file (e.g. $JAVA_HOME, etc). But when I come in over NX, it shows a totally different value for the $PATH variable, despite the fact that if I launch a terminal window (still in NX), and type export $PATH, it shows up correctly. I assume this has to do with which files are getting loaded by the windowing system over NX, and that it's some other file. But I have no idea how to fix it. For the record, I also have a .profile file with the following in it: # if running bash if [ -n "$BASH_VERSION" ]; then # include .bashrc if it exists if [ -f "$HOME/.bashrc" ]; then . "$HOME/.bashrc" fi fi

  • Spam mail through SMTP and user spoofing

    - by Josten Moore
    I have noticed that it's possible to telnet into a mailserver that I own and send spoofed messages to other clients. This only works for the domain that the mail server is regarding; I cannot do it for other domains. For example; lets say that I own example.com. If I telnet example.com 25 I can successfully send a message to another user without authentication: HELO local MAIL FROM: [email protected] RCPT TO: [email protected] DATA SUBJECT: Whatever this is spam Spam spam spam . I consider this a big problem; how do I secure this?

  • Fonts and encoding in windows live mail.

    - by Looser
    Sometimes I have non-english emails (arabic for example). When I try to open them with windows live mail, it doesn't show them correctly.. for example such this: &1588;&1603;&1585;&1575; &1610;&1575;&1605;&1575;&1606; (I changed it a bit to show here as I want) I had a look at options, there was encoding on arabic(windows) but I didn't find anything else.

  • IT merger - self-sufficient site with domain controller VS thin clients outpost with access to termi

    - by imagodei
    SITUATION: A larger company acquires a smaller one. IT infrastructure has to be merged. There are no immediate plans to change the current size or role of the smaller company - the offices and production remain. It has a Win 2003 SBS domain server, Win 2000 file server, linux server for SVN and internal Wikipedia, 2 or 3 production machines, LTO backup solution. The servers are approx. 5 years old. Cisco network equippment (switches, wireless, ASA). Mail solution is a hosted Exchange. There are approx. 35 desktops and laptops in the company. IT infrastructure unification: There are 2 IT merging proposals. 1.) Replacing old servers, installing Win Server 2008 domain controller, and setting up either subdomain or domain trust to a larger company. File server and other servers remain local and synchronization should be set up to a centralized location in larger company. Similary with the backup - it remains local and if needed it should be replicated to a centralized location. Licensing is managed by smaller company. 2.) All servers are moved to a centralized location in larger company. As many desktop machines as possible are replaced by thin clients. The actual machines are virtualized and hosted by Terminal server at the same central location. Citrix solutions will be used. Only router and site-2-site VPN connection remain at the smaller company. Backup internet line to insure near 100% availability is needed. Licensing is mainly managed by larger company. Only specialized software for PCs that will not be virtualized is managed by smaller company. I'd like to ask you to discuss both solutions a bit. In your opinion, which is better from the operational point of view? Which is more reliable, cheaper in the long run? Easier to manage from the system administrator's point of view? Easier on the budget and easier to maintain from IT department's point of view? Does anybody have any experience with the second option and how does it perform in production environment? Pros and cons of both? Your input will be of great significance to me. Thank you very much!

  • why do I get this mail server configuration error?

    - by Francesco
    <<The configuration of your mail servers and your DNS are not ok! The report of the test is: mail.mydomain.com. -> mydomain.com -> 78.47.63.148 -> static.148.63.47.78.clients.your-server.de Spam recognition software and RFC821 4.3 (also RFC2821 4.3.1) state that the hostname given in the SMTP greeting MUST have an A record pointing back to the same server.>> I have a A Record that points mail.mydomain.com to 78.47.63.148 (which is my given ip address for my vps) All other records are fine, so what's wrong and what record should I create to make it right?

  • Google Apps: MX records for zonefile

    - by 23tux
    Hi everybody, I have a question about using Google Apps for handling emails. I don't want to set up a whole entire mail system on my server, so I decided to use Google Apps. The ownership of my domain is approved, and now I'm trying to change the MX records in the zone file of my domain. But I think I'm doing wrong, it doesn't work. I want to use mail.mydomain.com as a adress to the mail server for POP, SMTP and IMAP. My zone file looks like this: $TTL 86400 @ IN SOA ns1.first-ns.de. postmaster.robot.first-ns.de. ( 2011011700 ; serial 14400 ; refresh 1800 ; retry 604800 ; expire 86400 ) ; minimum @ IN NS robotns3.second-ns.com. @ IN NS robotns2.second-ns.de. @ IN NS ns1.first-ns.de. @ IN A 111.111.111.111 localhost IN A 127.0.0.1 www IN A 111.111.111.111 ftp IN CNAME www loopback IN CNAME localhost mail IN CNAME @ relay IN CNAME www @ IN MX 10 ALT1.ASPMX.L.GOOGLE.COM. @ IN MX 10 ASPMX3.GOOGLEMAIL.COM. @ IN MX 10 ASPMX2.GOOGLEMAIL.COM. @ IN MX 10 ASPMX.L.GOOGLE.COM. @ IN MX 10 ALT2.ASPMX.L.GOOGLE.COM. I hope someone can figure out, what's wrong with this configuration. When I start a ping on mail.mydomain.org I get an answer from 111.111.111.111 and not from the google server ALT1.ASPMX.L.GOOGLE.COM. thx, tux

  • How to export User cert with private key in PKCS12 format

    - by andreas-h
    I'm running Win2008R2, and have installed an Enterprise CA. I can create user certs, but no matter what I do, I cannot export the private key. I'm using the un-touched User certificate template, and the "allow export of private key" option is selected. Still, whenever I go to the "export" dialogue of the certificate (both as user and as administrator), I don't get asked if I want to export the private key, and the option to select PKCS12 format is grayed out. Any help is greatly appreciated!

  • How faster is using an internal IP address instead of an external one?

    - by user349603
    I have a mailing list application that sends emails through several dedicated SMTP servers (running Linux Debian 5 and Postfix) in the same network of a hosting company. However, the application is using the servers' external IP addresses in order to connect to them over SMTP, and I was wondering what kind of improvement would be obtained if the application used the internal IP addresses of the servers instead? Thank you in advance for your insight.

  • looking for a free smpt server program.

    - by Richard
    Hello all, I am looking for a free smtp server. I am currently using Free SMTP Server http://www.softstack.com/freesmtp.html This software works great other than the fact that it can only send 10 messages a day. This is a bit of a problem seeing that the software I am writing needs to send a message every half hour. Anyone knows of a good piece of software that does the same thing, but does not limit the amount of messages that can be sent in a day? EDIT: I am using windows xp, so software must be windows friendly

  • Spam is Killing Me - Can I use GMail as a spam filter?

    - by kirkouimet
    I'm getting at least 50 Viagra ads a day and it's driving me insane. I currently have a hosted MS Exchange account and a Gmail account. My Gmail account forwards to my Exchange account. Both of my addresses are used evenly, and it has been really nice to have all of my e-mail end up in my Exchange box. I like replying from one address consistently, which is my Exchange address. Spam sent to my Gmail address is always caught, where spam sent to my Exchange is getting passed straight through to me. I don't want to have two spam filtration systems that have quarantines that I need to check frequently for false positives. Here is my question: Can I setup my MX records such that all e-mail sent to my Exchange address is forwarded to my Gmail account, which will then forward it to my Exchange account? Kind of like using Gmail as the middle man.

  • Outlook 2010 says "File is in use by another application or user" while closing

    - by A_Pointar
    Outlook opens, gets new emails and everything but when I close it, it gives me the following error and then opens up a Save a File window after I cancel this error message. There's no other computer that may be using Outlook under this User Name because I just set-up a brand new User Name. However, Colligo Briefcase is attached to the Outlook and not sure if this is triggering and if so how I address the issue!? Thanks a lot!

  • How can I migrate mails from Yahoo! Mail to Google Apps?

    - by alnorth29
    We'd like to move from using Yahoo! Mail to our Google Apps account. It'd be great to be able to migrate all the mails across from the old accounts to the new. If we were using Gmail accounts this would be easy as the migration is offered by Google, for some reason they don't offer this to those using custom domains. As far as I know Yahoo! don't offer POP or IMAP access to non-paying customers and I'd rather not pay $20 per account that I want to migrate. Anyone know of any easy and cheap solutions?

  • Dovecot starting and running, but not listening on any port

    - by Dženis Macanovic
    Among others things I'm in charge of a Debian GNU/Linux (Wheezy) DomU for the mail services of the company i work for. Yesterday one HDD that was used for this particular server has died. After installing Debian again, Dovecot decided to no longer listen on any ports (checked with netstat -l). Other services (like Postfix and MySQL) work without problems. dovecot -n: # 2.1.7: /etc/dovecot/dovecot.conf # OS: Linux 3.2.0-3-amd64 x86_64 Debian wheezy/sid ext3 auth_mechanisms = plain login disable_plaintext_auth = no first_valid_uid = 150 last_valid_uid = 150 mail_gid = mail mail_location = maildir:/var/vmail/%d/%n mail_uid = vmail namespace inbox { inbox = yes location = prefix = } pass db { args = /etc/dovecot/dovecot-sql.conf.ext driver = sql } plugin { sieve = ~/.dovecot.sieve sieve_dir = ~/sieve } service auth { unix_listener /var/spool/postfix/private/auth { group = postfix mode = 0660 user = postfix } unix_listener auth-userdb { group = mail mode = 0666 user = vmail } } service imap-login { inet_listener imaps { port = 993 ssl = yes } } service pop3-login { inet_listener pop3s { port = 995 ssl = yes } } ssl_cert = </etc/ssl/private/mail.crt ssl_key = </etc/ssl/private/mail.key userdb { args = /etc/dovecot/dovecot-sql.conf.ext driver = sql } protocol imap { mail_max_userip_connections = 25 } UID 150 is vmail (I double checked file permissions). I didn't install Dovecot from source, but via apt from the official Debian US mirror. There are no messages concerning Dovecot in /var/log/syslog except for: Oct 21 06:36:29 server dovecot: master: Dovecot v2.1.7 starting up (core dumps disabled) Any ideas?

  • Recommendations for good Unix MTA / groupware solutions? [closed]

    - by Jez
    Possible Duplicate: Exchange server replacement that runs on Linux I'm setting up a Debian server, and one of the things I need on it is an MTA. I don't want to use something like Exim or Postfix because I want something that ties in SMTP, POP3, and IMAP all in one (a la Microsoft Exchange). Most MTAs also seem to be hellishly difficult to configure. Try and read the Exim documentation; you could do a university degree on it (I'm not kidding). When you can get an HTTP server like Cherokee which is easy to configure and has a nice web interface, do MTAs or groupware solutions need to be that hard? I'm aware that some people think "the Unix way" is to have lots of different interacting pieces of software (like maybe an SMTP MTA, POP3 service, webmail service, and overarching manager to tie them all together), but I think this is a situation where that just makes things a lot harder to deal with and one large software suite fits in much more nicely. So, I'm looking for good open source software suites that will run on Debian that: Combine (at least) SMTP, POP3, and IMAP Are easy(ish) to configure Have a nice configuration web interface or GUI Are not defunct projects I don't mind if it's groupware and offers calendaring too, but I would only be using the e-mail functionality for now. Another nice-to-have would be built-in webmail (if we're combining a bunch of functionality, why not?) Note however that I do NOT need Outlook support. I am not really looking for an "Exchange replacement drop-in". The suites I've found so far that seem to match the above criteria (and have appropriate licenses) are Citadel, Kolab, and Zimbra. I'd appreciate anyone who has experience with any of these giving me the pros and cons of them, such as how easy they are to configure and what their performance is like. I'd also appreciate any other suggestions for solutions that fulfil my criteria that I may have missed out.

  • Authenticate with Django 1.5

    - by gorjuce
    I'm currently testing django 1.5 and a custom User model, but I've some problems. I've created a User class in my account app, which looks like: class User(AbstractBaseUser): email = models.EmailField() activation_key = models.CharField(max_length=255) is_active = models.BooleanField(default=False) is_admin = models.BooleanField(default=False) USERNAME_FIELD = 'email' I can correctly register a user, who is stored in my account_user table. Now, how can I log in? I've tried with: def login(request): form = AuthenticationForm() if request.method == 'POST': form = AuthenticationForm(request.POST) email = request.POST['username'] password = request.POST['password'] user = authenticate(username=email, password=password) if user is not None: if user.is_active: login(user) else: message = 'disabled account, check validation email' return render( request, 'account-login-failed.html', {'message': message} ) return render(request, 'account-login.html', {'form': form}) I can correctly register a new User My forms.py which contains my register form class RegisterForm(forms.ModelForm): """ a form to create user""" password = forms.CharField( label="Password", widget=forms.PasswordInput() ) password_confirm = forms.CharField( label="Password Repeat", widget=forms.PasswordInput() ) class Meta: model = User exclude = ('last_login', 'activation_key') def clean_password_confirm(self): password = self.cleaned_data.get("password") password_confirm = self.cleaned_data.get("password_confirm") if password and password_confirm and password != password_confirm: raise forms.ValidationError("Password don't math") return password_confirm def clean_email(self): if User.objects.filter(email__iexact=self.cleaned_data.get("email")): raise forms.ValidationError("email already exists") return self.cleaned_data['email'] def save(self): user = super(RegisterForm, self).save(commit=False) user.password = self.cleaned_data['password'] user.activation_key = generate_sha1(user.email) user.save() return user My question is: Why does authenticate give me None? I know I'm trying to authenticate() with an email as username but is that not one of the reasons to use a custom User model?

  • Adding Exchange Multi Tenant to an existing Exchange Network

    - by TiernanO
    I currently have an Exchange 2010 SP1 server in house, and due to some changes, it looks like i will need Multi Tenant support for a few extra domain names. Looking at the documentation i have found so far, it only mentions multi tenant support when upgrading from 2010 RTM - SP1, and not what you do if you have already got 2010 SP1 installed. So, from what i can gather, i have a few options: Install a new Exchange server with Multi Tenant support and migrate DBs over Back everything up and start again Something else... Any suggestions would be greatly appreciated... Thanks.
