  • Block by file type, but just file extension using MDaemon

    - by Arjun Rajagopalan
    I've had users sending copyrighted files (songs, videos) to each other over email. I blocked the file extensions .mp3 etc. What some users have done is to rename files to .doc etc. I cant block .doc etc filetypes because they are needed for day-to-day work. I'm using MDaemon 12 mailserver, Does anyone know how to make it block these attachments? I've been working on some content scanning for filetype code, but was wondering if there is a already made solution?

  • trigger script on postfix delivery errors

    - by edovino
    I'm trying to get postfix to run a script on soft (4xx) and hard (5xx) delivery errors, but I'm not sure where to start. If I understand things correctly, I could insert (pipe-based) filters in the master.cf file, there's a whole 'milter' infrastructure available, an finally I suppose I could simply grep through the mail.info logs. So - any advice? Should I go the 'handle it via master.cf' route, and if so, what daemon should I intercept? 'bounce'? The grep-the-logs route is probably simplest, but I can't help but feel that there is a better way. Any advice appreciated!

  • How can I change the subject of messages on an Exchange server automatically?

    - by Chris R
    I want to do something more than just normal mail - folder rules; I want to put a layer in front of my exchange server that lets me, for example, rewrite subjects into a more readable form. I get automated messages whose subject format makes them almost useless. Changing the emitting software is not going to happen, so I need to do something client side. I'm interested in anything that would allow me to do this, either on a mac, or on an older linux distro. Preferably the latter, and preferably in a way that I can turn on and forget about.

  • Inaccurate bandwidth limiting in altq queues

    - by overkordbaever
    I'm setting up an environment where I have one Linux server, one OpenBSD router and one Linux client and I want to be able to limit how much bandwidth the client should be able to use. I've been performing these tests with "netcat" and "time" (using time to measure the time of the transfer with netcat), and what happens when trying these tests (using the TCP protocol, the queues will for some reason not work with UDP) is that the queues aren't exact at all. For example: when setting a bandwidth limit of 10mbit, the client cannot use more than five mbits, when setting a limit of 100mbit, the client cannot use more than around 50mbit. The config looks like (using a 100mbit limit in the example): #queue rules altq on { $int_if, $ext_if } cbq bandwidth 100Mb queue { def, low } queue def bandwidth 0Mb cbq(default) queue low bandwidth 100Mb cbq(default) #Passrules test pass out quick from $int_if to $ext_if queue low pass in quick from $ext_if to $int_if queue low pass out quick from $ext_if to $int_if queue low pass in quick from $int_if to $ext_if queue low

  • How to allow a single domain name with iptables

    - by Claw
    I am looking for a way to make iptables only accept requests for my domain name and reject the others. Lately I misconfigured my apache proxy, it is now fixed, but I keep receiving a load of requests looking like that : xxxx.xx:80 142.54.184.226 - - [12/Sep/2012:15:25:14 +0200] "GET http://ad.bharatstudent.com/st?ad_type=iframe&ad_size=700x300&section=3011105&pub_url=${PUB_URL} HTTP/1.0" 200 4985 "http://www.gethealthbank.com/category/medicine/" "Mozilla/4.0 (compatible; MSIE 5.5; Windows NT 4.0)" xxxx.xx:80 199.116.113.149 - - [12/Sep/2012:15:25:14 +0200] "GET http://mobile1.login.vip.ird.yahoo.com/config/pwtoken_get?login=heaven_12_&src=ntverifyint&passwd=7698ca276acaf6070487899ad2ee2cb9&challenge=wTBYIo2AEdMFr6LtdyQZPqYw9FS9&md5=1 HTTP/1.0" 200 425 "-" "MobileRunner-J2ME" which I would like to block.

  • Is there a wildcard for setting up an outlook 2007 rule

    - by mikemurf22
    I would like to create a rule that moves anything with the words "SUCCESS * BenchmarResults", where the * indicates a wildcard to a specific folder. We have multiple systems that will be put in place of the *. We have emails that will return "WARNING * BenchmarkResults" that I don't want the rule applied to. I know I can create a seperate rule for each of our systems, but I want this rule to be dymanic where I can add new benchmark emails without creatting a new rule.

  • Free firewall for Windows Server 2003

    - by n00b_Admin
    We have a Windows Server 2003 R2 Machine here at work that I need to ensure is accessible only from specific set of IP Addresses. The Server is on a LAN and I am aware that one of the possible solutions maybe limit access to the Server's VLAN. However that is not feasible at the moment. I've been searching for a firewall that could do this, Windows' Firewall is pretty limited and I don't see an option in it to limit incoming data based on Source IP addresses. Most free firewalls like Comodo and ZoneAlarm don't work on Windows Server. Any ideas on how to accomplish this would be of great help. Thanks in advance.

  • Finding a way to enter gmail in Company

    - by stckvrflw1
    Hello all, I am entering network over DNS's of my company. Here my company blocks lots of IP's for reasons like entertainment, sports, music, messaging boards etc. General e-mail is also one of those topics and I can't enter gmail.com. The proxy sites are also blocked in the company and the one's I have found (by spending much afford) are not accepting cookies. Also I am not able to enter the gmail from Igoogle too, this is also blocked. How can I enter gmail ? Thanks.

  • Is there a way to redirect certain URLs to specific web browsers in Linux?

    - by jraxxo
    I'm using Chrome as my default browser in Ubuntu 12.10. I need to use Firefox for business purposes (certain websites pertaining to my work only work with Firefox). Is there a way to force Ubuntu to use Firefox for certain types of URLs (maybe as defined by a regular expression) while maintaining Chrome as my default browser for all my other tasks? Perhaps as a shell script running in the background? I'd like this to work system-wide, covering links from Chrome itself as well as PDFs/ODTs, etc. I have searched for solutions, but I couldn't find anything besides OpenWith, a Firefox extension which adds a button to open certain links in other browsers which would again require me to open Firefox beforehand, which does not help me at all. Does anyone have any ideas? Something like Choosy for Linux?

  • How to filter a mysql database with user input on a website and then spit the filtered table back to the website? [migrated]

    - by Luke
    I've been researching this on google for literally 3 weeks, racking my brain and still not quite finding anything. I can't believe this is so elusive. (I'm a complete beginner so if my terminology sounds stupid then that's why.) I have a database in mysql/phpmyadmin on my web host. I'm trying to create a front end that will allow a user to specify criteria for querying the database in a way that they don't have to know sql, basically just combo boxes and checkboxes on a form. Then have this form 'submit' a query to the database, and show the filtered tables. This is how the SQL looks in Microsoft Access: PARAMETERS TEXTINPUT1 Text ( 255 ), NUMBERINPUT1 IEEEDouble; // pops up a list of parameters for the user to input SELECT DISTINCT Table1.Column1, Table1.Column2, Table1.Column3,* // selects only the unique rows in these three columns FROM Table1 // the table where this query is happening WHERE (((Table1.Column1) Like TEXTINPUT1] AND ((Table1.Column2)<=[NUMBERINPUT1] AND ((Table1.Column3)>=[NUMBERINPUT1])); // the criteria for the filter, it's comparing the user input parameters to the data in the rows and only selecting matches according to the equal sign, or greater than + equal sign, or less than + equal sign What I don't get: WHAT IN THE WORLD AM I SUPPOSED TO USE (that isn't totally hard)!? I've tried google fusion tables - doesn't filter right with numerical data or empty cells in rows, can't relate tables I've tried DataTables.net, can't filter right with numerical data and can't use SQL without a bunch of indepth knowledge, not even sure it can if you have that.. I've looked into using jQuery with google spreadsheets, doesn't work at all either I have no idea how I'm supposed to build a front end with my database. Every place that looks promising (like zohocreator) is asking for money, and is far too simplified to be able to do the LIKE criteria or SELECT DISTINCT stuff.

  • Need help with implementation of the jQuery LiveUpdate routine

    - by miCRoSCoPiC_eaRthLinG
    Hey all, Has anyone worked with the LiveUpdate function (may be a bit of a misnomer) found on this page? It's not really a live search/update function, but a quick filtering mechanism for a pre-existing list, based on the pattern you enter in a text field. For easier reference, I'm pasting the entire function in here: jQuery.fn.liveUpdate = function(list){ list = jQuery(list); if ( list.length ) { var rows = list.children('li'), cache = rows.map(function(){ return this.innerHTML.toLowerCase(); }); this .keyup(filter).keyup() .parents('form').submit(function(){ return false; }); } return this; function filter(){ var term = jQuery.trim( jQuery(this).val().toLowerCase() ), scores = []; if ( !term ) { rows.show(); } else { rows.hide(); cache.each(function(i){ var score = this.score(term); if (score > 0) { scores.push([score, i]); } }); jQuery.each(scores.sort(function(a, b){return b[0] - a[0];}), function(){ jQuery(rows[ this[1] ]).show(); }); } } }; I have this list, with members as the ID. And a text field with say, qs as ID. I tried binding the function in the following manner: $( '#qs' ).liveUpdate( '#members' ); But when I do this, the function is called only ONCE when the page is loaded (I put in some console.logs in the function) but never after when text is keyed into the text field. I also tried calling the routine from the keyup() function of qs. $( '#qs' ).keyup( function() { $( this ).liveUpdate( '#members' ); }); This ends up going into infinite loops (almost) and halting with "Too much recursion" errors. So can anyone please shed some light on how I am supposed to actually implement this function? Also while you are at it, can someone kindly explain this line to me: var score = this.score(term); What I want to know is where this member method score() is coming from? I didn't find any such method built into JS or jQuery. Thanks for all the help, m^e

  • filtering directly and indirectly connected things from list

    - by Andreas Romeyke
    Hello, if you have a function "test a b" which returns true if a and b are connected directly and if you have a given unordered list of things, what would be an elegant and fast solution to filter all connected things from given list? Example: let test a b = let diff = a - b in diff == 0 ;; let lst = [4;1;7;3;8;9;2;0] ;; filter_connected 2 lst ;; - [4;1;3;2;0] Any hints?

  • Controlling Solr score/sort

    - by Znarkus
    I want to filter a property within a range, but items that does not have the property should come last in the result. My solution was to set it to -1 if the property was not set. +(property:[10000000001 TO 10000000019] property:"-1"^0.5) This doesn't work, since every document with property:-1 get a very high score, for some reason. Is there a way to reliably control the sorting here? Boosting the range instead would mean I must boost every other term, which I'd rather not do.

  • Jquery: get ancestors (or descendants) and self

    - by gsakkis
    One can use matchedset.find(selector) / matchedset.parents(selector) to get the descendants/ancestors of the current matched set filtered by a sealector, but that doesn't include the matched set itself (if it happens to match the selector too). Is there a better (more consise and/or faster) way to get it than matchedset.find(selector).add(matchedset.filter(selector)) and the respective for parents() ?
