Hi Matt,
When you create a new mail account, say, mailbox@domain.com the "domain.com" mail domain is added to SmarterMail domains automatically. "Mail.domain.com" domain is the result of DNS A record with the name "mail" which is also added to the appropriate DNS zone.
Let me know if I correctly understood your question.
Yes, we'll add SmarterStats support in the retail release. Serv-U and Gene6 FTP providers will be added too. All major service providers will be added till the end of this year.
