This usually is a DNS issue and/or Email Server Alias issue. Or a combination 
of both.

See 
http://www.solarspeed.net/otrs/public.pl?Action=PublicFAQ&CategoryID=3&ItemID=16 
for a full explanation.

If your site is named "www.company.com" in the GUI and has the Email Server 
Alias "company.com", then this is the minimum set of DNS records you ought to 
have:

 company.com	 	---- A Record ----> 	 <IP-Address>
 www.company.com	 ---- A Record ---->	 <IP-Address>
 company.com	 	---- MX Record --->	 www.company.com (*)
 www.company.com	 ---- MX Record --->	 www.company.com (*)
 <IP-Address>	 	---- Reverse ---->	 company.com (***)

(*) = This MUST be the exact name (including the hostname part) of the domain 
as shown in the GUI interface.

(***) You must have reverse delegation authority for that network address in 
order for this to work. Or ask your network provider to set up a reverse for 
you. Or at the worst check that your IP has a reverse record already.

Any other records (mail.*, ftp.*, etc.) are optional.
