Sendmail not delivering mail from outside

02/11/2006, 12h40

Alright, I have a CentOS 4.4 server that I manage with
Webmin/Virtualmin. I have Sendmail 8.13.1 installed by default with
yum.

I only have a problem with it accepting mail from outside sources. The
users can receive mail sent by another local user and they can send
mail perfectly. When I try to send an email to an account on the server
with Gmail, it doesn't make it to the user's mailbox. I don't see
anything in the maillog about it, and I don't receive any "returned to
sender" message.

I have all the domains in the local domains file.

Any ideas?

Did you setup DNS mx records properly?

Is your sendmail server accepting connections on a publicly reachable
IP address or only on the loopback address, as per the typical modern
distribution defaults?

Ah, it was configured to the loopback. When I checked the "Default" box
in Webmin, everything started working again.

Thanks!
