spamassassin attachment scanning

Question

I have just started using spamassassin for my email server.

I am unable to find an answer for following questions:

1. Does spamassassin scans attachments?

2. If not, what plugins can be used for the same.

As far as I can comprehend spamassassin can dmime an attachment and can scan it if it's in a plain format (like html, txt etc), Is my assumption correct?

Thanks in advance

Answer 1

Yes, it will scan them up to X kilobytes, where X is defined by --max-size parameter given to spamc, or for example the message size limit configured in amavisd-new.

What kind of attachments SpamAssassin will scan is depending on what kind of unarchivers and viewers you have installed. I you don't have (un)zip installed, don't expect SpamAssassin to dig through zip archives ... :-)

Answer 2

Spamassassin will scan the first X kB of each message-part (where X is configurable).
