Virtual Users And Domains With Postfix, Courier And MySQL - Postfix Problems

[rculley]

Having followed the Virtual Users And Domains With Postfix, Courier And MySQL howto on FC several times I still keep getting the same problem. If I do "echo test | mail user@domain.com" the mail folders are created fine and I can login and view the mail no problem.

However, if I try to send the mail from another network to the domain on this server it never arrives and there's no log of it in maillog! In BIND I have the MX record for the domain configured as follows:

domain.com. IN MX 10 mail.domain.com.

and an A record pointing the FQDN to the IP:

mail.domain.com. IN A ip.ip.ip.ip

Everything else is working fine on the server - Apache, MySQL etc and mail sends to other networks OK.

My /etc/postfix/main.cf file is as follows (some standard commented lines removed):-

I'm assuming that it's a DNS issue or something similar as mail addressed to the same address arrives if sent internally. The machine is directly connected to the Internet in a colocation datacentre configured with two public IPs and there are currently no firewalls blocking any ports.

/etc/hosts:

-----
# Do not remove the following line, or various programs
# that require network functionality will fail.
127.0.0.1 localhost.localdomain localhost
ip.ip.ip.ip domain.com domain

I'd be really grateful of any help as it's been driving me crazy the last two days!

Thanks

Sorted, working now! I was sending from an old server which used to have the domain configured on it so it was just spooling internally!
