When a user's mailbox is showing set in mailenable as well as in plesk but you still get an error during delivery try this

** Goto %plesk_dir%/mailservers/mailenable/config

**  Take a backup of ADDRESS-MAP.TAB 

** Open ADDRESS-MAP.TAB in wordpad

**************************************************************************

You should see mailboxes in this format >:-

 

[SMTP:abuse@securediscovery.com]    

[SF:securediscovery.com/harry] 

      

 securediscovery.com    0

Each mailbox MUST be in one line,

 

if you see a line break eg;

[SMTP:abuse@securediscovery.com]   

 [SF:securedisry.com/harry]          

 securediscovery.com    0

Edit the text and make sure its in ONE line.Almost all the time, when a line breaks, 

some characters are missing,so when you edit-make sure the there are no missing characters 

in that line,This is very important and should be done carefully.

<< Important  >>:-

Once this is done, restart mailenable and test that mailbox.
