Another email question

[Pamster]

We have noted that when the ring email address is different than the ring
host email address, that the From field of notification messages says:

From <ringhost.email@xxxxxxxxxxx>; on behalf of

<ringowner.email@xxxxxxxxxxx>

Where it doesn't show that if they're the same.  Is there any way to
suppress that, other than having the emails the same.  If you leave the
address out of the config file, does that cause other problems?
