Just moved to a new server and will not need the Mailenable 3.0 Professional Perpetual license for Unlimited Domains/Mailboxes
that was used on the old server.
It's the latest version of mailenable that allows for unlimited domains, POP Retrieval, Web Mail, Web Administration, Enhanced Anti-Spam, Content Filtering, Antivirus Protection, MailEnable COM Component, and much more. It normally sells for $280.
Check out this link for more info - http://www.mailenable.com/pro_edition.asp
The transfer of this is totally legit and allowed by mailenable that is done through their online services interface.
This transfer can happen as soon as needed by the buyer.
