As of right now..
DNS resolution is flaky.. Some times i get an answer, sometimes I see a SERVERFAIL reply i can not receive e-mail. (they bounce back..) I am however to use the page, and send e-mail to an external server
I have a VPS, running CentOS 5.4 I left the default hostname that was given to it from the provider
I was given 3 ip addresses when i bought the VPS I picked one of my domains.. and set the glue records and created a host for each of the addresses
I then took those 3 fqdn and used them for all of my other domains at the registrar
For some of my domains i take the mx record within virtualmin and change it to point to the GMail servers. Others i leave alone and let my server host the e-mail
For the longest time i thought that the problem was simply with my dns server not responding(slow?) to queries on the mx record, Now i believe there is a configuration error on my part.
I have recently tried to send (web)mail on the server itself to another account on a different domain, Both to an account where the mx record points to google and where the e-mail is on the same server.... I can send e-mail to another domain completely, but i can not send e-mail to any domain that is on that server, regardless of where the mx record points.
Gmail will bounce an e-mail back with the following reply Connection was dropped by remote host (SENT_RCPT)
I cant get the DNS resolution to fail right now.. but sometimes i simply see a SERVERFAIL message...
.... Not sure if this is the same problem, or just one really screwed up installation, with many issues... I simply don't know where to go right now.
99% of the install is default from virtualmin..
what did i miss?
