Then using tail -f /var/log/maillog, I got the error: Mar 9 10:28:48 myserver postfix/smtpd[73796]: fatal: parameter "smtpd_recipient_restrictions": specify at least one working instance of: check_relay_domains, reject_unauth_destination, reject, defer or defer_if_permit
I put in a hash mark for the smtpd_ line in main.cf and ran another postfix stop and start to get mail working again, but what am I doing wrong with the file?
Read the error message - currently you are configured to accept *any* message presented except those going to the specified users. That includes spam intended for completely unrelated domains. I would recommend using the following as a *bare* minimum:
smtpd_recipient_restrictions = permit_mynetworks, reject_unauth_destination, check_recipient_access hash:/usr/local/etc/postfix/access
I would also recommend looking at
http://www.postfix.org/SMTPD_ACCESS_README.html and
http://jimsun.linxnet.com/misc/postfix-anti-UCE.txt -- they will help you
understand what should be in your smtpd_*_restrictions.
I saw the errors and googled for it, but it just led to the man pages and site web pages for the postfix project (which I read); what was throwing me was the fact that it wasn't an open relay before and it didn't have the directive previously. I think it was using reasonable defaults before and my adding that line to my main.cf overrode them causing it to burp the error messages.
