While leaving the "reply to" address blank may have been OK in the past, large ISPs like YAHOO!, GMAIL, and OUTLOOK, are now actively vetting to make certain that the SENT FROM and REPLY TO e-mail addresses and domains match - exactly.
That is why we always set our user's accounts up with a REPLY TO e-mail address which is identical to the e-mail address built in SmarterMail, eg:
If I build a new user, on the domain name, "bar.com," and the user's name is 'foo", then the e-mail address is "firstname.lastname@example.org"
So, that would be the address I would put into the REPLY TO address field in the user configuration in SmarterMail.
So, after I've built the user in SmarterMail, this is what a typical user's configuration screen looks like:
Note that our standard mailbox size is 15 gig. Exchange licenses get 25 gig.
It would be nice if SmarterTools would consider this as a default for future versions of SmarterMail.
