What do the logs say about the message?

Why did you remove them?

/etc/email-addresses
       is  used to rewrite the email addresses of users. This is particularly useful for
       users who use their ISP's domain for email.

       The file should contain lines of the form

       user: someone at isp.com
       otheruser: someoneelse at anotherisp.com

       This way emails from user will appear to be from someone at isp.com to  the  outside
       world.  Technically,  the  from,  reply-to,  and sender addresses, along with the
       envelope sender, are rewritten for users that appear to be in the local domain.

This is from the manpage for exim4-config_files. /etc/email-addresses
and /etc/aliases _do_ share a common format. Their function is
something entirely different.

What does "ip addr" show?
