Thunderbird sending mail

Have you tried telneting into SMTP using its FQDN to see if it is
actually accepting connections?

~]# telnet my.mail.server 25

Also check /etc/resolv.conf does have the correct name server. It could
be that hosts on the WAN are resolving fine, but local FQDN are not.

In my case, for example, I've set my router as the DNS, which then peers
to my ISP, therefore DNS resolution works transparently for both the LAN
and the WAN, regardless, provided I always uses the router's IP for all DNS.
