Mail to Vodafone.mobileemail.net stuck - returning Connection terminated with status: 2562

About four or five times in the last couple of months, emails addressed to @mobileemail.vodafone.net sit in the mail.box whilst emails to other internet domains are sent successfully. Emails to @mobileemail.vodafone.net previously have been delivered without any problems. If I restart the router task the emails are then delivered immediately.

The following is reported in the Log (with SMTPClientDebug=1 enabled)

1/11/2008 19:57:31 [0670:000E-044C] SMTPClient: Attempting to Connect: Host MOBILEEMAIL.VODAFONE.NET, Port 25, SSL Port 0, Connecting Domain rtsmail.realtimestore.com

01/11/2008 19:57:32 [0670:000E-044C] SMTPClient: Connection terminated with status: 2562

01/11/2008 19:57:32 Router: No messages transferred to MOBILEEMAIL.VODAFONE.NET (host MOBILEEMAIL.VODAFONE.NET) via SMTP: Remote system no longer responding

This has occurred with both Domino 8.0.1 and 8.0.2. Any ideas as to whether it is a problem with Domino, mobileemail.vodafone.net or the network?

We are also running Trend ScanMail for Domino 3.0 SP3 Patch 4 on this server.

Thanks

Subject: Answer is in what you posted.

“Remote system no longer responding”

Your server is not able to see the remote server anymore. Either the server is down, routing issue or it is not accepting requests from you.

Can try doing a trace route to the DNS address. If that works try manually connecting to SMTP port with a terminal app and see if you get a response. See more here.

Subject: same error for me

have an 8.0.2 Domino SMTP trying to send to mail.messaging.microsoft.com and getting the " terminated with status: 2562" error. have you figured anything out as to what is causing this error message?
