Looking at the headers of some of my messages I would expect to get:
Received: from remote_host (HELO remote_host) (IP.Add.re.ss) by nefw.net with (RC4-MD5 encrypted) SMTP; 27 Jun 2007 16:39:30 -0500
When using 127.0.0.1 as the resolver rather than the default 1and1 settings, the domain (bold above) rotates randomly through all the virtual hosts. Any way to set this to be a specific hostname? I think it would be rather strange for customer Y seeing headers from customer X.
I kinda figured. All the rest of the headers are accurate, just that one changes. Strange that it would pull info from someplace other than the "me" file for that one thing, but at least it works I suppose.
You probably have a PTR record for all of your domains. Don't do that. I don't know why the default DNS template has a PTR record, but that's probably how you got in this situation.
Yeah I was going to remove that in the template, but I wasn't sure if it would break something else. I was planning on testing this weekend, but it sounds like it's a non-issue.
