Your question is clear.
This cannot be done with netfilter (because all imap connections look the same to netfilter, no matter what client or server software is being used)
I cannot think of another way to do it either, because I would be surprised if Outlook sent anything in its connect message to identify itself as Outlook (the server end of a connection often does, but the client end usually doesn't, except for web browsers).
Sorry - but perhaps someone else here can prove me wrong?
Regards,
Antony.
