It seems to me this is all backwards. info@domain should have been set up
as a separate role mailbox, to which sally as a user with her own mailbox
has the rights to connect to and send mail as from. (I am not an Exchange
administrator, so do not know the exact terminology!).
I may have missed it, but what is expected to happen if a message is
addressed:
To: info@???, info@???, somethingelse@???
How is whatever system supposed to determine which the outbound reply
message should use for the From?
I would either leave the 'solution' as it is, or persuade the company that
what they want doesn't really make sense, or re-implement things within
Exchange to provide a more sane environment. Despite some interesting
implementation suggestions, getting Exim to try and make this environment
work will be a challenge. Maybe it is time to re-address the reasoning
and go back to basics.
