I've been having trouble getting mail to the domain CCMAIL.uhc.com. I received the following message. Does anyone have any advice on what I could do on my end, as listowner? Or is it a problem that needs to be solved by someone on the receiving end? Any suggestions would be appreciated... When bounced back to me, the listserv says they are not delivered due to "ambiguous address." Yet private mail seems to arrive. Is there documentation specific to these problems that I could request. Yeah, I'm new ;-) -Geff listowner Hepv-L [log in to unmask] > Subject: Re: Not getting through... Geff, Your list server is getting registered improperly in our mail switch. If you could send me (using your account geffreyt) the address of the account that is attempting to send the list messages, I would correct the registration.
