Allow save copies of message option to be set by account

[Vespasian]

Hello,

I'm using IMAP for the first time, but also have POP3 accounts with no IMAP
support in Outlook 2007.

I want to save a single copy of my sent messages, after they are actually
sent. I can't do this in OL 2007, or at least if I can, without a bunch of
rules tinkering and/or negating a benefit of IMAP.

I don't like the rules setup, because it sends a copy of my POP3 e-mail to
the sent items folder when I hit the send button, not when the e-mail is
actually sent.

I'd like to have the ability to set the option of saving copies at the
account level. Now, either I can't save messages for my pop3 accounts after
they're actually sent from my outbox to the outgoing server, or I have to log
in to my IMAP account via Web and set the account to not keep copies of sent
items, or else I get duplicate copies of sent mail in OL.

Feel free to correct me if I'm missing something. I figure with a zillion
people using OL, this issue has come up before, but I don't see anything
having been done to accommodate the situation.
