Horde webmail interface shows each email in the folder (Inbox, Sent, Draft etc.) with 'Invalid Address' as a sender and 'No Subject' as a Topic. Moreover, each of those emails are shown to be 0B size and delivered (sent) in the same time.


Horde cannot not parse the data provided by MailEnable from '_index.xml' file that contains the information about the emails in the folder.


  1. Open the physical mailbox folder:

      %plesk_dir%\Mail Servers\Mail Enable\Postoffices\<domain_name>\MAILROOT\<username>\Inbox
  2. Remove '_index.xml' (it will be generated automatically again).
