Unable to get Hobbit 4.2 to send e-mails

[Jason Hand <jason (at) hands4christ.org>]

Hey Everyone,

This is the second Ubuntu server I have set up with Hobbit 4.2 and  
Postfix as the SMTP server and the first one had no issues but this  
second one is having trouble.

If I telnet to the server and send an e-mail manually it works with no  
problems but what is appearing in the notifications.log shows that it  
is generating the alert but no e-mail is sent according to the postfix  
logs.  I can see the manual e-mail in the postfix logs but nothing  
from the hobbit alerts.

Any ideas of what I can check?

It is using the 'mail' command to send mail, but so is the other  
Ubuntu box and it sends just fine.

Thanks for any suggestions.
