There is a big problem with a lot of POP clients, with the "lookup
for new mail interval".
If the client doesn't get the eMail within that timeout it gets an
interupt, hangs up the current transfer, does a "LIST" and starts over
and over and over ...
Other things are e.g. firewalls that put limits on the amount of data
that is allowed to be transferred during one POP session (*sigh*)
I've also seen cases where the POP client doesn't handle "disk full"
situations (on the client disk) correctly.
What we do if everything else fails is call the customer and do a
transfer under control of e.g. tcpdump.
We had cases where the client simply "hard" closed the TCP connection
during transfers without any CLOSE/FIN whatever packets and refused to
talk any more (Windows environments). Reinstalling the client mostly
fixed the problems.
Hope that helps.
