Hi all, I am attempting to configure a test mail server (postfix) on an OpenBSD machine, but have run into a problem that I can't seem to find on Google or elsewhere. When I run postfix, I am able to telnet into my mail server from outside of my local network, and send an email to firstname.lastname@example.org. I have configured the aliases file to link the webmaster account to root, and after the telnet session I run mail as root, and I can see that I have properly recieved the message. However, when attempting to send an email from another mail server (ex: gmail or yahoo mail), the mail does not show up in /var/mail/root and /var/log/maillog has no additional entries. Also, there is no mail failure message returned to my yahoo/gmail accounts. I have checked my MX records and ensured that they resolve to the correct IP address. I believe this may not be a postfix-specific problem, as I created a quick sendmail configuration and had the exact same problem with that as well. If anyone could point me in the right direction, I would appreciate it.
