    Anti spam for Linux


    Hello all,

    I am interested in installing an anti-spam and anti-virus software on a Linux
    server that caters to some 500 users.

    Can anyone suggest a good anti-spam software and if possible send a
    link for some documentation about its configuration..

    Thanks a lot

    Hello Kriss,

    Thanks a lot for the link... Can you please let me know how effective spamassissin is on Linux. I am using sendmail and is there a good documentation for spamassassin to be used with sendmail as a spam filter. I checked the spamassassin.org site but it has little information about configuration.

    Thanks a lot for your valuable time

    I'm using spamassassin on my system and I find it quite effective.
    The most common way to use spamassassin is to include in your ~/.forward file. Add a line that reads "k007: |spamassassin" to filter all mail through spamassassin (providing that your username is k007 (forgive me, but I'm having a hard time respecting that you're using h4x0r markup)). Note that sendmail (providing that you're using sendmail) executes these things via smrsh, so you'll need to either install a copy of spamassassin in /etc/smrsh, or disable the use of smrsh (less recommended).
    The above method is, of course, only valid for a seperate user. If you want to enable spamassassin to all users, I suggest configuring sendmail to run spamassassin instead of procmail.

    Hello,

    THanks for the responses and suggestions. As per the suggestion for spamassassin to be used with sendmail, what changes are to be done to sendmail.cf file and since I want it for a site-wide configuration do I have to individually create .procmailrc file with the contents for all the users ( in our case it is more than 500 ) ?? or is there any other way for a site wide configuration.... Some documentation regarding configuration of spamassassin over sendmail will be really a great help

    Thanks

    Thank you everyone

    I have got good amount of information from all of you and now I have got a tar of spamassassin . But nowhere I found what exactly I need to add in my sendmail.cf file after I install spamassassin. Is there any thing particular that needs to be added in the sendmail.cf file for sendmail to use spamassassin or just creating local.cf file in /etc/spamassassin and running the spamd daemon will do.

    Thanks

    Well, the thing is that with its normal usage (ie. without -P), spamassassin just forwards everything to procmail directly. In that case, you only have to replace the "local" mailer with spamassassin (it should currently be procmail), and all should be done.
    However, it doesn't really work that way if you use spamd. spamc only emulates spamassassin with its -P behaviour, ie. it outputs the scanned mail on stdout. Therefore, if you want to use spamd (which I guess that you want), the best way is probably to write a procmail recipe to pipe everything through spamc. I haven't written any procmail recipes myself, but check the manpages (see procmail(1), it has references to a couple of others) and you're sure to find out.
