each Mahghany folder starts with a message with the

This message gets 3.5 of 5 points to be classified as spam by Spam Assassin.
Maybe there could be introduced a special header field which
marks this special message (e. g. X-Mahogany: Folder internal data - don't
delete this message) so that the spam-alike phrases could be avoided?
How fun! I never considered how this message would be scored by SpamAssassin!
;-)

Out of curiosity, how is this message being fed to SpamAssassin?

IIRC, the usual method of feeding messages through SA is from a server-side mail delivery agent (MDA), such as Procmail. Since this dummy message is folder meta data, it never passes through the MDA. On the other hand, if you have SA running on the client side, I would have thought that the POP/IMAP server would not (should not) relay this message to the client. The only way I can think of at the moment that SA would see this message is if the entire raw mailbox is fed through SA.

It is possible to tailor one's own local SA configuration to score emails a little differently. For example, one could add a test for this particular message and bias the score towards a positive non-spam value. In this situation, were I to be trying to deal with this issue, I suspect I would investigate this option.

I'm curious about this issue, by the way, since I'm toying with hooking SA into the client side, hence I'm interested in whatever issues might come up.

Incidentally, AFAIK, the dummy message you refer to is not generated by Mahogany, hence an X-Mahogany header would probably not be appropriate.

Or maybe this internal message could be avoided at all?
Again, AFAIK, the message is generated by the POP (and possibly IMAP) server, and is necessary to keep mbox state-information. Without it the POP server would continually "rediscover" every message in the mailbox, and begin renumbering all message UIDs, with the result that everything would always be a new message.

Then I've seen that there are some mailers which are treated as "brave"
mailers by Spam Assassin. I think Mahogany is not among them. See
file 20_anti_ratware.cf.
Here is a link to the SA configuration file:
<http://www.spamassassin.org/dist/rules/20_ratware.cf>

I thought this file only specified tests for either (A) mailers that were commonly used as the MUA for spammers, or (B) forged mailer headers that were commonly found on spams? Have I misinterpreted the uses of this config file?
