[SOLVED] reject_unknown_hostname

[sanford]

Is it possible to make a single exception for one of our vendors who does not have A/MX records?

They seem to get caught up in "reject_unknown_hostname" in postfix, and I'd rather not disable this, just for this one individual company.

Thanks!

Under the smtpd_recipient_restrictions you could have something like check_sender_access hash:/opt/zimbra/conf/validdomains and within that file you would have

service.domain.com  OK

and then as the zimbra user execute postmap /opt/zimbra/conf/validdomains. You will want that access map to execute before reject_unknown_hostname.

Excellent, just what I was looking for.

Thanks!
