Things to check:
1) Thoroughly check network connectivity to the mail server from the
problem clients.
2) Any possible file locking conflicts? Is there anything running on
the server, possibly antivirus software, that might be locking the email
in the server's mail directory?
Thought of what could be happening here:
a) Client retrieves all mail via pop3, marking them for deletion.
b) Something on the mail server is still holding the files open for
read (on demand AV scanner maybe?)
c) Client quits the pop3 session, and the messages marked for
deletion are now supposed to be deleted
d) Because one of the email messages is locked for read (see: "b",
above), Xmail is unable to delete files, and gives up.
e) Mail has not been deleted, and will be re-downloaded on next pop3
session.
Davide would be able to comment on the possibility of "2d" happening on
Xmail. I have no idea if it could even happen, so I may be way off base
here -- but short of a network connectivity issue, I can think of
nothing else at the moment.
