Thanks for the input John,

Mostly access will be accomplished over MAPI or IMAP(handhelds) which is documented to be encrypted. Sendmail is another option we looked at but
the BUY IBM mentality has set in!

>Robert, how will you pick up the mail- by individual machine POP? If so, is the stream encrypted- because otherwise all your company e-mail, including confidential internal memos, will be transmitted in the clear across the internet.
