| Mail from my IIS 6.0 SMTPSVC is sticking in the queue. It is being passed to
a smart host which is an exchange 2000 server.
I turned on full logging and get:
2005-03-21 04:25:46 10.88.0.30 OutboundConnectionCommand SMTPSVC1
SENDINGSERVER - 25 EHLO - sendingserver.mydomain.com 0 0 4 0 0 SMTP - - - -
2005-03-21 04:25:46 10.88.0.30 OutboundConnectionResponse SMTPSVC1
SENDINGSERVER - 25 - -

SENDINGSERVER - 25 BDAT - 823+LAST 0 0 4 0 0 SMTP - - - -
Then... nothing happens.
I'm guessing something is going wrong in the binary data transfer.
If I specifically turn off the EHLO greeting for the receiving domain, the
mail gets through.
Sorry if I'm late to the party and this is a well known bug, but I seached
the group and couldn't find a reference to it.
Anyone got any fixes? I'd be happy to turn-off EHLO completely on my IIS 6.0
server if there's a reg key to do it.
Any help gratefully accepted.
