Yes, if fetchmail sees an error from your local MTA, it tends to not delete
the message from the remote site, because it thinks there's a problem. You
*can* tell it what a spam reject on your local MTA is, however.
For example, I've got a few checks at the postfix level that will reject a
detected spam message before it ever *gets* to the user's mailbox. As
such, spamassassin isn't coming into play yet. Spam that it detects, it
rejects with a 550 error code. You can tell fetchmail that a given error
code (or range of codes) is a spam reject and to not attempt redelivery
(I.E., it will go ahead and delete the message from the remote server).
Here's what I have in my .fetchmailrc to do this:
set postmaster "postmaster"
set bouncemail
set no spambounce
set properties ""
poll <remote host> with proto IMAP
user '<blah>' there with password '<blah>' is '<blah>' here
antispam 550
That last line ("antispam 550") tells it that a 550 code coming from
postfix on my machine is a spam reject. It will then quietly delete the
message from the far end as though it had delivered it. Try putting in the
reject code that you're seeing at your end from your local
postfix/qmail/sendmail daemon, and see if that helps.
