and the ISP wasn't interested in the wireshark traces.

I know, I should change the ISP and see if the problem goes away. :-)

[Dovecot] retr errors

[Bill Morgan]

My ISP uses Dovecot and I have had an ongoing problem
for a while using several email clients.

Sometimes the response to a retr request is mal-formed. The expected 
response

"+OK nnn octets" is not returned. The response looks like it
started somewhere in the message headers.

Sometimes a retry can clear the
problem but I usually need to delete the first message via a putty session.

The problem, when present, is always on the first message. Never seen
it in the middle of a series of messages. This problem has been seen on
different machines, different versions of Windows, at home and on the road.

I have wireshark traces showing good and bad sessions

My ISP has been non-helpful. Any ideas how I can track
down the problem?
