Try UseNet News groups:

DNS issues:
        comp.protocols.tcp-ip.domains
        comp.protocols.dns.bind

SMTP issues:
        comp.mail.misc
        comp.mail.sendmail

If you don't have access to a real news server, there are several
web gateways/archives.

When your secondary gets mail, how do you know that your primary is
reachable from the standpoint of the remote sender?
Internet routing issues can get very strange on occasion.
