IMAP trouble with Pegasus
Claus Ruge
I never had any problems with IMAP and Pegasus Mail over the last 6
months, testing Pegasus in our software and hardware environment in the
office (privately I'm using Pegasus Mail since version 2.4x).
But this has changed. The reason might be that in the past I only
received short messages with Pegasus, but recently I had to download
some larger mails with data files as enclosures (a few hundred KB to
about one MB) and the problems occur only while downloading such larger
messages.
I made a log to see what happened and there are some things that look
strange to me but I'm not very familiar with the IMAP protocol. I'm not
able to decide if this is a Pegasus related problem or a problem of the
IMAP server. Maybe someone here can give me some enlightenment. Here are
the shortened logs, with some comments added and slightly re-formatted:

Okay, transmission of message starts here and everything seems to
work fine. But suddenly, while data still being downloaded...

UBE/UCE mails to any of my addresses are definitely not allowed. Sending
such mails to my addresses constitutes an agreement of the sender and/or
responsible but non cooperating provider to pay me a downloading, pro-
cessing and archiving fee of US$ 500,00.

I wonder if MS Exchange actually counted the message's size incorrectly such
that WinPMail thought it ended sooner. I'll have to check with David Harris
on this one.
We may need to see the full exact debug message though (username and
password removed, of course).

I could check the file size and it was 644132 bytes long.

From the log I posted to the group I only snipped out some megs of
base64 encoded data, but it contains all the conversation between
Pegasus and the IMAP server. And I fear I already deleted the complete
log.....
BTW, it was possible to download such large files with other programs
such as Netscape and "The Bat!". This doesn't mean that Pegasus is
faulty, it could also be that those two programs are more tolerant of
misbehaving servers.
