Today I did an upgrade of our mail server from Lotus Domino ver 7.04 to 8.5.1 (FP1). The upgrade went well. However I am encountering a very strange problem. Outgoing e-mails are not being delivered. They are remaining inthe mailbox. Incoming e-mails are coming in fine.
I keep seeing the following warning message on the Domino console:
“Failed to connect to SMTP host gov.mt because the connection has timed out”
I tried doing an nslookup on the mail server but didn’t get any results.
What could be the reason for this problem? I have tried to solve this but without success. Could this issue be related to our ISP? I’ve checked our fw and it isn’t blocking anything. We were sending e-mails fine until yesterday. I am suspecting the Domino upgrade. I’ve never experienced this before and I’ve done various upgrades!

If you run the command “sh stat mail” from the Domino console do you see any errors or messages like “Mail.WaitingForDNS=xxx” If the number is greate than 0 then you may have a DNS issue.
