I have setted up sendmail on my CentOS server with webmin installed. I've added a few important mail aliases such as this:  -> to ->

Now when I send an email to, I get no email in my hotmail inbox, it's been a few hours with no email yet.

How come this isn't working? I can send emails to my hotmail inbox via a PHP script from the server but I cannot send email and get it forwarded by the alias email?

I looked in the /var/log/maillog and I don't see any errors there. What can be happening?

Before you answer, sendmail is running.

Hotmail has responded the email that I just sent earlier:

This is an automatically generated Delivery Status Notification.

Sendmail cannot read directly the /etc/aliases file, so every time you make changes to it, you must run the newaliases command to update the database. Maybe you forgot to do that?

I'm sure webmin does that already, I ran that command and made a new email and still nothing in my inbox. – MacMac Jul 3 '11 at 17:34
Hm, is your sendmail configured to accept mails for It works with system account by default, not sure if Webmin does anything to fix that. – Vladimir Blaskov Jul 3 '11 at 17:42
