Thanks a lot for your report.
Actually, this appears to be a bug I've introduced in popa3d 0.4.9.3.
Before this version, popa3d would often include the mailbox separator
trailing empty line in messages. I decided that I don't like this
(the line is a part of the mailbox format, not a part of the messages)
and killed this property in 0.4.9.3. Unfortunately, this lack of an
empty line triggered a bug in Outlook Express (now worked around in
0.5.9 by still adding the empty line whenever necessary for MSOE), and
as you have now noticed I forgot to update the reported message length
accordingly. I wish someone who uses fetchmail reported this earlier.
Other POP3 clients clearly don't do this check because it doesn't
really affect anything (there's a more reliable way to see when a
whole message has been received).
Please test the patch below (against 0.5.9) and let me know if it
solves the problem for you. I will then include it in the release.
