Windows 2000 Server SP4 Exchange 2000 SP3 Over the past few days I have noticed that for one external site, SMTP mail regularly builds up, introducing delays of up to an hour before delivery.
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?
