OK, I stopped the Groupshield service, the problem remained. Email flowed as expected to other external destinations OK, yet to this particular domain (@dial.pipex.com) it queues up. Then after a several mintues the odd mail gets through again.
When I restarted Groupshield the symptoms were the same, mail queues up, same error message. Then suddenly a few email get through. I'm completely baffled! Thanks for the suggestion though. -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Sander Van Butzelaar Sent: 24 February 2004 13:38 To: Exchange Discussions Subject: RE: Mail queuing up in SMTP Virtual Server It is worth getting any AV software out of the way just for a quick test (not suggesting that you run production systems without AV!) at least it is something you can then take out of the possible problem category. Give it a try.

I initially thought there must be a problem with the external companies SMTP service, but then realised the timeout error message was being generated by them and not me! Therefore my SMTP virtual server is sitting there at the DATA prompt doing not a lot, and then getting timed out by the remote server. I forgot to add I am using Groupshield 6.0, could this be interfering?

I have checked the SMTP logs for the Virtual server and can see that the connection is timing out:- 62.241.160.71 - OutboundConnectionCommand [24/Feb/2004:11:37:36 +0000] "EHLO -?mailhost.gap.co.uk SMTP" 0 4 62.241.160.71 - OutboundConnectionResponse [24/Feb/2004:11:37:36 +0000] "- -?250-funhouse.systems.pipex.net SMTP" 0 30 62.241.160.71 - OutboundConnectionCommand [24/Feb/2004:11:37:36 +0000] "MAIL -?FROM:<[EMAIL PROTECTED]>+SIZE=3665 SMTP" 0 4 62.241.160.71 - OutboundConnectionResponse [24/Feb/2004:11:37:36 +0000] "- -?250+Ok SMTP" 0 6 62.241.160.71 - OutboundConnectionCommand [24/Feb/2004:11:37:36 +0000] "RCPT -?TO:<[EMAIL PROTECTED]> SMTP" 0 4 62.241.160.71 - OutboundConnectionResponse [24/Feb/2004:11:37:37 +0000] "- -?250+Ok SMTP" 0 6 62.241.160.71 - OutboundConnectionCommand [24/Feb/2004:11:37:37 +0000] "DATA - SMTP" 0 4 62.241.160.71 - OutboundConnectionResponse [24/Feb/2004:11:37:37 +0000] "- -?354+End+data+with+<CR><LF>.<CR><LF> SMTP" 0 35 . Several other connections to other sites are mentioned in the log files, then this line pops up! . . 62.241.160.71 - OutboundConnectionResponse [24/Feb/2004:11:47:42 +0000] "- -?421+Error:+timeout+exceeded SMTP" 0 27 The SMTP Virtual Server is working fine for other external sites, so I'm a little confused!! The mail entry is marked up for a retry and eventually goes through. I have manually connected to the external site in question using Telnet and the remote system is performing as expected, there are no excessive delays. Can anybody shed any further light/suggestions?
