Hi,
we are encountering the following problems if we try to send mails to a certain foreign domain. If we try to send an smtpmail the server returns
Router: No messages transferred to XXXXX.DE (host mail.XXXXX.DE) via SMTP: Network operation did not complete in a reasonable amount of time; please retry
The “foreign” Admin sees that our server tries to connect to him, but then… SILENCE. It looks like both servers are waiting for the opposite one to start talking. I am able to send mails via telnet from the same machine. Debugging of the SMTP-Task shows nothing special.
Our server used to be Release 5.11. The problem started all of a sudden. We thought that upgrading to 6 (6.03) would maybe solve the problem but with not success. The opposite Server is also an Domino 6.x but I don’t know if this is relevant…
Any thoughts?
Thank u in advance!!
