Hello.I´we just installed a domino server and there is a long time since iwe done anything in domino so i assume this is a simple problem to solve.

I am trying to make the server send mail and the mail wont go out… firewall is disabled.

Router: Failed to connect to SMTP host RTFM.IS because : The server is not responding. The server may be down or you may be experiencing network problems. Contact your system administrator if this problem persists.

log

29.03.2005 19:01:59 Router: No messages transferred to RTFM.IS (host mx2.dynamicsystems.dk) via SMTP: Remote system no longer responding

29.03.2005 19:02:03 Router: Failed to connect to SMTP host RTFM.IS because Remote system no longer responding

Any suggestions ??

Thanks in advanced

Based on my own experience, never get too stressed about one host not responding. A lot of smaller companies have Internet connectivity issues and go down once in a while–especially if they change Internet service providers and the DNS entries get messed up.If you can send email to other sites (try emailing yourself at a free email account) the problem is more likely on their end.

Another thing you can do is telnet to them on port 25. If you get a connection error, they are probably not up.

Syntax as follows:

telnet servername 25

Good luck!

Hi, It looks like your domino server is unable to contact remote host via 25 port(SMTP).

Try to make a telnet session from your server to 25 port.

for example:

telnet mail.hotmail.com 25

I think you should also check whether firewall does not block outgoing SMTP connections.

Have you upgraded antivirus software on you server? some of antivirus programs has built-in firewalls.

I am also having the same issue. I can connect via a laptop on the network but my Domino cannot connect to any outside SMTP. I have looked into everything (Firewall, etc.) I can’t telnet to any SMTP outside of my network. What was the SMTP fix?
