dovecot - Dec 2004 - Timeouts with outlook express

Hi

I am using Dovecot 0.99.12.1 (just upgraded) on a site with about 1500
mailboxes. One thing I have noticed is when the client outlook express
is receiving a large mail via pop3 it gets a time out. There is traffic.
If you click on the "wait" button in the dialogue the mail continues
to
download. 

This seem to relate to the "Server Timeouts" setting under mail
account
Properties/advance. If this setting is set higher the dialogue come only
after this time has passed.

If the mail take a long time to download if say is very big the user may
have to click "Wait" a number of time even if the time  out setting is
set to the largest amount.

It funny because the mail is downloading, So the pop3 server has not
stopped responding as outlook express say it has. Strange.

What is happening here? and is there a work around for it. Do I have a
setting wrong. 

Regards
Daniel ROwe

The only thing "wrong" here is Outlook and the only workaround is not
to
use it. We're an ISP with a several 10000 users and I had 100yen for 
each time this happened, I could retire. 

This did happen long before we used Dovecot as well, btw.

Amazing... it's still doing this?  I saw the fruits of this wrongheadedness 
some years ago.  Users were complaining that they were receiving the same 
message repeatedly, and no more.

What was happening was Messenger/Outlook/OE was downloading the message, and 
decoding the attachment, then timing out and so not telling the POP server to 
delete it.  Why they decoded the attachment before confirming the 
receive/deleting the message on the server, who can say...

Wonderfully stupid design which you'd think they'd fix eventually...
then again...

Hi

Yes I have all the outlook workarounds enabled.

Interestingly the progress bar dose not move until the whole email has
been downloaded. Normally this moves bit by bit as the mail downloads.
But as I said the email is downloading, there is network traffic.

Any ideas?

Regards
Daniel
