Postfix Spam Filter using Ubuntu Dapper, MailScanner, SpamAssassin, Razor, Pyzor, DCC

[rapidos]

Hello I followed this howto:
Postfix Spam Filter using Ubuntu Dapper, MailScanner, SpamAssassin, Razor, Pyzor, DCC and ClamAV

Everything worked fine but since I got mailscanner on board mails dont get delivered anymore ...

Sep 16 17:17:26 gate MailScanner[2211]: Virus and Content Scanning: Starting

but nothing more... It looks like the mail scanner starts but never ends ..

Has anyone an idea about this issue ?

Thank you for your help

Do the other logs contain any errors?

Hi falko,
I just figured out that the system was trying to acces to the mount point /var/spool

so i added a new partition and mounted it properly on /var/spool

I ran the LINUX2 command again, set right permissions according to the "postfix check" command and now I'm in another trap:

I'll go through the howto once again and recheck everything, but if you have any idea, please let me know !

Cheers,
Julien

Ps: thanks for your time ;-)

I also tried to run

postfix set-permissions

but It always asks me for files that doesn't exist on my system.

I tried to download many of them, but I just not stop to ask me more and more files ...

[rapidos]

Ok,
never mind !

I reverted to an eralier snapshot (thanks vmware)

I moved everything from /var/spool to a backup dir

and then mounted /var/spool

and removed everything into the proper directory.

Now I'm still running in the trap that I encountered at the beggining of the post :'(

Thanks for everything

[falko]

I'm sorry, but I don't know where this problem comes from.

[rapidos]

Hey falko,
I tried to run freshclam and the update failed, so I tried to upgrade it but it didn't work.

So I uninstalled clamav and now emails are getting delivered.

The only problem is that an email containing words such as viagra is not detected as spam .... How could I be sure that spamassassin, pyzor, and dcc are really working ? Is there a delay before spamassassin starts to notify an email as spam ?

Thanks a lot for your help

No, but SpamAssassin is learning from your emails, so it will become better over time.

[rapidos]

Ok,
so, just to be sure, it is normal that spamassassin doesn't mark one single e-mail that contains the word viagra because it just doesn't know what it is (yet) ?


I thought that some basic rules would have been implemented to prevent from such e-mail that just can't be false positive ...

Thanks for your help falko

[falko]

If you simply write an email with the word viagra in it, it would hardly count as spam. SpamAssassin runs hundreds of tests to find out if an email is spam or not. The existence of a single word is not enough.
