mailutils - mail command, problem with the From address

  • Posted February 14, 2015

I installed mailutils to use the mail command but when I use it the emails get rejected in the other end because the domain of sender address does not exist. In fact, the domain is not correctly set (it is the hostname, not the domain).

How do I fix this? I need to set the domain name correctly so mailutils can see it.

When you installed mailutils, you should have been prompted to enter a “System mail name.”

postfix debconf

To re-run this initial setup, run:

sudo dpkg-reconfigure postfix
