When I get the model, I will post it. The user is traveling at the moment.
Let me try to explain the set up better. His primary email address is
. That is, hisdomain.com is his own domain name on his own server along with his web site. A copy of each email sent to
after it is spam filtered. Should he change carriers, which is likely, all we have to do is point his email address to the new provider. So that's not a problem. Since he also POPS his email from his own server through Outlook at home, he can always get his email, even when AT&T is down.
I assume that BIS is the setup page I mentioned (att.blackberry.com). While I don't see "BIS" written anywhere, the tab says "Blackberry Internet Service", so I assume that's correct. He's definitely not using the Enterprise service.
So just to be clear, if I set up a new IMAP account in BIS (I do have his user name and password), all I have to do is wait 20 minutes, and the account will automagically appear on his Blackberry. I don't understand what the service book is, but if all he has to do is respond to an activation notice, then you have answered my question.
