I follow your document and everything on postfix is ok except this error when i try to start mailscanner:

Starting MailScanner...
/opt/MailScanner/bin/check_mailscanner: line 53: MailScanner: command not found

If you can sent me the mailscanner.conf or help me with this i'll be very grateful.

Thanks for the HOWTO!

Did you know there is an effort being made to get MailScanner in portage?

Hey great how to.

One question, why MailScanner over amavisd-new? Just curious because I have used amavisd-new in the past and have never tried MailScanner before.

carlito,

Not sure why you are getting that error. The MailScanner command should be in the same directory as check_mailscanner. Either way I've been helping with getting a MailScanner ebuild up and going. Ther has been alot of work on it from alot of people. I hope it will get into portage soon. See bug above until then. Thanks!

Jeremy

Your welcome!

Yep knew about the bug page and have helped out. I see you are helping as well. Great! This was my quick attempt to help those until the ebuild gets in portage.

whitetux,

Never heard of amavisd until now. Thanks for the tip. One of the great things of open source is choice. I gave those who wanted a choice a HowTo on one of those choices. Why not write up a HowTo on amavisd?

I had a look at amavis earlier, it was more difficult to install, required modifications to my mail server setup and was not able to do spam checks at the same time. I am *VERY* pleased with MailScanner it is far superior than any commercial package available on the market.

But as said, open source is all about the freedom to choose

I can't get my setup working. I copied over /var/spool/postfix to /var/spool/postfix.in, copied /etc/postfix to /etc/postfix.in, and did all the necessary changes. The init script started up just fine, but it won't deliver any mail. This is from an already working postfix setup (I'd been using it for a while and decided I wanted to implement clamav for my windows users.) Once I undid the changes to /etc/postfix, got rid of the mailscanner init script, and re-loaded the normal postfix script, mail is delivered again. I'm afraid that I won't be able to play with this for a while now since I have others depending too heavily on my server. Guess I will have to wait until later

Any ideas anyone?

There is already a pretty stable MailScanner ebuild getting worked on. You can check out the bug referenced above.

To answer your question though. Check /var/log/maillog (or your mail log location) and see if MailScanner is complaining about any permission problems. I have had the same issue you are having in the past and it has either been a permission problem or a typo in my MailScanner.conf or in main.cf. Good luck and sorry it didn't work right of the bat.

I solved my problem, i do a symlink of ln -s /usr/bin/MailScanner /opt/MailScanner/bin/MailScanner and now everything is working

carlito,

there is an option in the MailScanner.conf that will configure what it should do with spam, highly marked spam, and viruses. You can store, deliver, bounce, etc each one of those options. Check in the conf file and take out deliver on the appropriate config line. I would tell you the exact line, but I'm to lazy to look it up

Good luck.

Also Mailwatch @ http://mailwatch.sf.net is a great tool to use with MailScanner, but not for the faint of heart. Back up your conf files before trying this. I learned the hard way

Mirrors is at http://footon.jheslop.com/howto/anti-virus-spam-howto.html

also there is a mirror at http://wiki.linuxquestions.org search for MailScanner (should be back up soon there)

Hey thx for this great tutorial. It was exactly what I was looking for. I have done the same install using exim on another machine. It works well too.

Thx

Great HowTo, but is it possible to set it up so that SpamAssassin can be customized by each user of the system? I looked at the configuration and it appears that is should already be doing it, but when I add an account to the blacklist, it still gets through without any tagging.

Thanks

vector0319

I'm not a hundred percent sure about that. Intuition would say it should work for each user especially since, like you said, it states so in the conf file. You should contact the MailScanner maintainer Julian and should be able to answer your question a little better: mailscanner@ecs.soton.ac.uk

Hope this helps and you get it working for you.

No joy for me

I tried this HOWTO to implement mailscanner and spamassassin in my existing postfix/clamav/cyrus solution (clamav had been being called by evolution).

The first sign of trouble was this error when installing the Convert::BinHex perl module. Here's the output of make test:

tutlendog,

Usually when I want to add a perl module I either see if the module is in the portage tree, use the "perl -MCPAN -e shell" command, or the g-cpan.pl command. There is headway on making a MailScanner ebuild here: https://bugs.gentoo.org/show_bug.cgi?id=36060 In this ebuild there are references to the packages needed for MailScanner to run. If the package is not in portage you can run g-cpan.pl instead like so:

Also on your statement

Isnt convert-binhex in portage? I have been using the portage version and have 2 successfull installations of mailscanner. Have I been using a wrong convert-binhex?
