HiOur servers Windows 2003 SBS with Lotus Domino 8.0.2 on it have stop sending email to outside clients email accounts. it gives an error massage of
SMTPClient: Connection terminated with status: 2055
Anyone have any ideas what this means
Thanks in advance
Subject: check your connections
Check your connections from the server to the outside world. Can you ping (some outside server) from the Domino server OS? If you do a trace to a known external mail server, where does it break down? This could be a problem with a router or pipe, or could even be a change to firewall restrictions.
Subject: Email
Do you know of any email severs I could try that would be up and running ?
Subject: check log, test online first
Check your log for mailservers you’ve sent to in the past. Then go to this page and click on the link for the SMTP test utility, and follow the instructions. This will enable you to verify that the external mail server is up and accepting your messages.http://www.zoneedit.com/lookup.html
Then you can test from your server’s OS.
You could also test sending an emtire message from your server’s command line instead of via Domino. Use telnet:
telnet 25
HELO youremailaddress@yourdomain
MAIL FROM:
RCPT TO:
DATA
.
QUIT
Subject: Looks like…
It is connectivity…

But if you want to concentrated on past causes of this error:
Network Router having issues resolving addresses
Proxy misdirecting traffic over port 25 to wrong or nonexistent servers
Firewall blocking outbound port 25
Firewall/Mail Relay Host server overloaded or otherwise unresponsive
Using an incorrectly configured multi-homed NIC or dual NICs
So verify your network connectivity. Check your server configuration document to be sure you don’t have it set to relay through another server that is down or no longer exists.
