I have a situation where a user is trying to send mail to a domain that has 2 mail servers listed in the MX record. The primary mail server, I am told, is blocking port 25 for all but a few select IP addresses and we are NOT one of the few who are allowed to connect. Whenever I try to send mail to anyone at this domain I get a 421 error in the logs and the message is sent back after 25 attempts. It never tries the secondary mail server when sending mail. IPswitch says it should work this way so is the destination mail server setup at fault? The only way I can see to fix this would be a host file entry for the secondary mail server.
The domain we are trying to send mail to is: business.queensu.ca I was wondering if anyone has ever come across a situation like this.
