Hi..thanks for the suggestion, and this is actually what I did.
6.3.2 has the exact same problem. I posted full a full trace to
fetchmail-devel on berlios, but nobody has replied so far. Maybe
I really should have posted on the users list instead(?)

Anyway, I got impatient and tried to debug the code myself, and
the result is the following patch to 6.3.2. It completely fixes
the problem for me..but I'm unsure if I did the Right Thing.
Not really being familiar with the code I can't be sure it won't
break on other IMAP servers, but it works like a dream on mine,
and I get my mails instantly, without the poll delay.

Here's the patch (also posted it to fetchmail-devel on berlios):
