[rt-users] RT not using CorrespondAddress

[Simon Walter]

I have this in /opt/rt4/etc/RT_SiteConfig.pm

Set($rtname, "example");
Set($WebDomain, "example.com");
Set($Organization, "example.com");
Set($CorrespondAddress, "support at example.com");
Set($CommentAddress, "support at example.com");

And I get email from:
"Internal Todos and Reminders via RT" <support.com at manage.example.com>

I change it to:

Set($rtname, "example");
Set($WebDomain, "example.com");
Set($Organization, "example.com");
Set($CorrespondAddress, "support");
Set($CommentAddress, "support");

And I get email from:

"Internal Todos and Reminders via RT" <support at manage.example.com>

Better, but still not correct. Yes, the machines host name is manage. Yes it 
is a subdomain of example.com that exists on the local network. No, 
example.com isn't what I'm using. It's just an example.

What gives?

How can I get RT to actually use the address I specify?
