I just finished following this tutorial to set up a postfix mail server on ubuntu 14.04:
When I tried sending an email to
firstname.lastname@example.org from Gmail, nothing shows up in
/var/mail. There is no file there. But when I send an email from email@example.com to the Gmail account, the email sends fine.
The tutorial doesn't go in-depth enough to know what's going wrong so I was hoping I could get an answer here.
