The postoffice and mailbox levels filters are for inbound emails arriving to a mailbox. So when an email is being delivered, it will process the postoffice level filters and then the mailbox filters. It does not apply mailbox and postoffice filters to emails being sent out by a mailbox in a postoffi...

Check the headers of the email received to see what it was send as. i.e. try checking Return-Path of the email and see if it matches what they have entered in the whitelist (and make sure it is not in the blacklist).

Can you check the following registry key:

[HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Mail Enable\Mail Enable]

Check through the file to see if any of the names have a problem. Otherwise please send it to our "sales at mailenable.com" email address and they c...

If you want all new mailboxes to be added to the directory when created you can set this as an option in the administration program.

The API generally works only on the configuration items that match what they are called. So the list API items only work on lists, but for a list to be able to receive an email, it needs an address map, i.e. a route from an SMTP address to a list address.
