[ZendTo] Re: Message to recipient showing IP Address instead of DNS name

[Sergio Rabellino]

I have UseCanonical set to Off and the urls are constructed correctly 
with the FQDN name of my virtualhost.
As a reference:

How are you calling your server in the browser url ? If you use the IP, 
probably then you'll get the IP on the email.
Which browser/version are you using ?

Into the lines you pinpointed, it's used $_SERVER['HTTP_HOST'] instead 
of $_SERVER['SERVER_NAME']: i agree with you, the second is better 
because it's related to the request's headers and not to the server 
configuration. I suggest Jules to exchange these as the values at the 
worst case are identical.

hope this helps.
