This is only an attempt at deduction but...

If the filtering acts on the mailboxes on a remote IMAP server, then it
will take place on your machine (the IMAP server can't know about your
Eudora's filters) but affect the mails held on the IMAP server, so it
will need to communicate back to the server to work.

So it will take place between the two locations and if your coms are
b0rked, it should fail, typically with a spinning Frisbee of death,
requiring a force quit.

This is *not* from personal experience, so may be quite wrong. But it
seems likely to me...

Indeed. But then what's the point of having an IMAP server rather than
POP3? Becasue POP3 is what you seem to be describing.

Yes. And that's (POP3) that you described in your post. Viz:

"The fetching mail process is actually 2 sub-processes: 1) downloading
messages; 2) filtering them. I would think that after having
accomplished 1), that 2) happens locally. The act of retrieving messages
should already have deleted them from the server."

In which case I'd have expected that (a) the messages would continue to
be held on the server until you explicitly deleted them and (b) the
messages on the server would be affected by your filtering choices-
otherwise everything on the server would be an unsorted mass of mails.

Of course I could well be wrong. But it seemed to me that there would be
some kind of sorting/deleting that would go on that would require a
connection with your computer- and it seemed to me that that was the
problem your were describing at the start.

I don't use IMAP, so I may well have totally misunderstood how it works.
But I don't see the point of it unless it retains a sorted mailbase on
the server.

Like Peter, I don't use IMAP but my understanding of it matches his.
I'd recommend (if you haven't already) that you download the full manual
and study the section relating to IMAP. The manual is a huge PDF and
doesn't automatically download when you download Eudora; you have to
makke a special download of the manual from the Eudora site.

Dave,

By filtering the IMAP mailbox you are defeating the benefits of the IMAP
protocol.
The imap process only downloads the headers of the messages in your mailbox.
For the filtering process, the body has to be downloaded as well.
If besides the filtering you have an anti-virus application that scans
your emails for virus, that might be the issue. Each message gets
scanned by every filtering rule you have.
Your issue appears to be a result of "idle timeout" whereby the server
does not receive any communication during a set period which might be as
short as 60 seconds.

You should explore whether your provider offers filtering on the server
for the incoming email.
