[ale] odd email issue

[Geoffrey Myers]

So, I've got sendmail configured so it uses localhost for sending email. 
  As a normal user I can send email like this:

date|mail email at domain

Yet, I've recently configured /etc/aliases to send root email to my 
personal email address:

root:           email at domain

But I get delayed email messages from 1and1, my domain host for these 
emails because my machine name (centsovm.serioustechnology.com) is not 
valid.

So, how is this possible?
