Tárgy: [Exim] Outlook timeouts
Hi.

I have Exim v4.24 running on Windows XP using Cygwin and Outlook as a
client. Outlook intermittently hangs while sending mail and I'm
reasonably confident that the problem is a Microsoft "feature". I have
seen that Postcast has a special option to handle Outlook clients and
I'm hoping that somebody here may be able to help with something similar
that I can tune to get past Outlook's behaviour.

As you can see from the log below, everything seems to be fine and Exim
seems to be working correctly. The connection starts, Exim says Hello,
Outlook responds with the MAIL FROM, Exim send OK and then Outlook shuts
up and nothing else happens.

It seems to be linked to particular messages as I can sometimes get the
mail to go through by deleting the blocking message from Outlook but
it's not at all predictable and I have no idea why particular messages
cause this behaviours. My best guess is that it is a timing thing and,
for some reason, outlook is missing the OK.

Any suggestions?
