You wouldn't happen to be using Scanmail 3.82 would you? I noticed _exactly_ the same thing happening with large(ish) messages (some but not all).

I still need to log this with Trend, whatever's doing it, it doesn't seem have any problems with inbound messages. regards, Paul > -----Original Message----- > From: Fyodorov, Andrey FTL [mailto:[EMAIL PROTECTED] > Sent: 19 February 2004 04:11 > To: Exchange Discussions > Subject: Exchange 5.5 SMTP timeout > > > One of the Exchange 5.5 servers at this place has a few large > messages in > its outgoing IMC queue and can't send them. > > Normally the server sends all outgoing mail to a couple of > Exim boxes.
