Woohoo! sendmail+cyrus+MailScanner+spamass-milter working!

[wizard]

Finally got all the mail functions back that I had *before* upgrading to FC2

spamassassin was the one I did the most headscratching over - and then I found the most excellent spamass-milter in Dag Wieers' repository.

I installed the milter, added

INPUT_MAIL_FILTER(`spamassassin', `S=local:/var/run/spamass.sock, F=,T=C:15m;S:4m;R:4m;E:10m')dnl

to sendmail.mc, ran

make -C /etc/mail

restarted sendmail, spamassassin and spamass-milter just for grins and am now happily filtering mail through spamd again. Life is good.

Actually I ended up ditching MailScanner for clamav-milter. Much better performance - at least on my machine.

Here's the tutorial

1. Get sendmail working with cyrus.

2. Install spamassassin and spamass-milter.

3. Install clamav and clamav-milter.

4. Add the following two lines to /etc/mail/sendmail.mc (check paths to the sockets - these worked on my server):

INPUT_MAIL_FILTER(`clamav', `S=local:/var/clamav/clmilter.socket, T=S:4m;R:4m')dnl
INPUT_MAIL_FILTER(`spamassassin', `S=local:/var/run/spamass.sock, F=,T=C:15m;S:4m;R:4m;E:10m')dnl

5. From a terminal session, issue 'make -C /etc/mail'

6. Insure sendmail has permission to talk to the sockets. This wasn't a problem in FC2 for me.

7. Make sure ScanMail is uncommented in /etc/clamav.conf

8. Start clamav, clamav-milter and spamd.

9. Restart sendmail.

Note: My setup will still pass mail if clamav-milter fails - you may not want this. If you want to bounce mail if clamav-milter fails use this line in sendmail.mc instead:

INPUT_MAIL_FILTER(`clamav', `S=local:/var/clamav/clmilter.socket, F=T, T=S:4m;R:4m')dnl

enjoy!

And here's a mail header that shows it all working. I rewrite subject lines with spamassassin and then use a client filter to move the mail to a spam folder

Hey Wizard, thanks for the little tutorial. I got this setup working also except that the subject line of the spam email doesn't get re-written as such. Spamassassin recognizes the spam and inserts the X-Spam headers, but it won't insert ***spam*** into the subject line. I'm thinking that I got to add something to the trusted users section of sendmail. Got any ideas? Thanks.

Hi, blammo -

In this instance rewriting headers is a function of spamassassin, not sendmail

Here's the relevant part of my /etc/mail/spamassassin/local.cf

rewrite_subject		1

subject_tag		***spam*** spam count=_HITS_

You'll need to restart spamassassin for this to take effect, I think.

Hope this helps -

Thanks wizard! I found the problem to be in the startup script for spamass-milter. Apparently there is a -m arg that disables subject rewriting. Removed this little puppy from the startup script, and now it's happily rewriting the subject line. Powerful setup here! Thanks again.

[wizard]

Damn. I forgot about that

Thanks for pointing it out, blammo - enjoy the new mail toys

How do you get sendmail to forward mail to cyrus ???

update: I figured this out and finished the article covering this topic.

Thanks

Hi I am new user in fedora server, I read carefully this forum and the forum starts with using mailscanner. Then is used clamav-milter and spamass-milter.
I found webpage mailwatch for mailscanner, it seems the mailwatch is good staff.
It is possible to find something similar for the second solution with clamav-milter a spamass-mitler?
Thanks
