Hello,
I am having an issue with email on all IP-based site/accounts that I set up on CENTOS 6.3 x86_64 standard – WHM 11.34.1 (build 5). On the server's main IP address domain account/site, both sending and receiving email works just fine, however, on all IP-based accounts/sites I create the email users can send email but not receive it, and dnsstuff.com shows:
All connections to Mailservers port 25 have failed. The standard port for SMTP transactions is 25, so your servers should be operating on that port. It is recommended that it be fixed in order for your mail service to operate properly. The Mail Servers that failed are:
198.24.145.122 | failed message send with: messaging failure: Time out occurred or Remote server closed connection prematurely
I have tried multiple solutions but haven't been able to get email working properly. Any ideas would be appreciated.
The default firewall rules do not allow connection to port 25. Have you enabled smtp for your local firewall?
(I hit this one myself!)
