I'm not writing this to promote or lambaste someone else's product. This product looked promising from the positives reviews on another site. I am considering a switch to another server application and have concerns about converting/migrating the mailboxes from my present server. I sent them an email with this querybut it has been about a week now and have not received a reply. If they don't pay attention to inquiries from a potential customer, I wonder how they treat their present customers. Not encouraging at all...

this is totally overpriced for what it offers.

if you are running Panther, then take a look at the $9.95 shareware Postfix Enabler (Note: I am not affiliated with the author). Postfix enabler (in combination with what comes already with 10.3) has more features and far fewer limitations - in particular, no limits on the number of user accounts.

if on the other hand you want to spend money on a professional mail server package, then go for CommuniGate Pro (Note: I am not affiliated with the vendor). CGP cost a little more, but it has everything you would want to have this day and age: POP and IMAP, various secure authentication methods, Webmail, anti SPAM features at the SMTP server level and just about everything is configurable on a per user basis. Post.Office does not even come close to be a candidate for a comparison.
