[fetchmail]timeouts and stuff

[F. Heitkamp]

I use fetchmail/sendmail/procmail/spamassassin. I've continued to tweek my 
settings and have managed to get rid of a lot of problems causing messages 
that stay on the server and get retrieved multiple times. However there 
are still messages that mysteriously cause problems. I have examined these 
messages and I can see nothing obviously wrong (to me anyway)  with them. 
I assume fetchmail gets some sort of error from either 
sendmail/procmail/spamassassin that causes it to assume the message has 
not be successfully delivered.

One possibility I've been thinking lately is that it seems my pop account 
from my ISP seems to be set to timeout after only a few seconds. How I've 
determined this is that if I use Pine to retrieve messages the server 
kicks Pine off after several seconds and I have to start over with the 
original pop mailbox.  Mutt on the otherhand seems to detect the server 
closing the mailbox, saves the mailbox state and logs in again.  I've 
looked through the fetchmail FAQ and man pages, but I can't seem to find a 
setting that would limit a connection to, say, 20 seconds. Even better if 
one could get fetchmail to detect the mailbox closing like Mutt does. 
Does anyone know how I might set up fetchmail for either of those two 
cases?

Logically though, I'm not too confident that the timeout casue above is 
really the problem because it is only specific messages that seem to cause 
problems, not random ones.  When I look through my fetchmail log I see, 
for example, 351 fetchmail: reading message 
heitkamp@mailhost.day.ameritech.net:26 of 36 (4108 octets) fetchmail: 
flushed
     352 fetchmail: reading message heitkamp@mailhost.day.ameritech.net:27 
of 36 (20794 octets) fetchmail:  not flushed

Looking through the mail and message system logs gives no answer for the 
"not flushed" that I can see other than the occasional "Timeout waiting 
for draining input", which happens far less than the number of messages 
left on the server. Is there a debug setting that will tell me why the 
fetchmail refused to "flush" a certain message, or does fetchmail just get 
some sort of generic SMTP error.
