Summary: Fetchmail Fails with ASSP (http://assp.sourceforge.net/)

Details: Hi There,

I am trying to download messages from a catchall mailbox and forward them on to a mail server that sits been an ASSP installation.

The problem I am having is that ASSP only looks at the first 2000 bytes of the message in order to determine whether it is SPAM or not.

If the message that Fetchmail is sending is larger than this size and ASSP considers it to be SPAM - ASSP closes the connection with a 550: response before Fetchmail has finished copying the mail.

Fetchmail then errors with Query status=6 (IOERR)

It does not delete the message or mark it as seen.

next time fetchmail logs in try's to send the message again with the same result.

I can increase the amount of bytes that ASSP looks at and while this solves the issue temporary it is not a permanent solution.  ASSP was not designed to look that the whole message.
When I increase the amount of bytes ASSP looks at the system resources go through the roof.

Is it possible that Fetchmail could somehow recognise the 550 response from ASSP half way through message sending.

I have enclosed log file for you to look at

Hope you can help 

Regards

Phil
