[horde] problems searching in imp

[Ralph Ballier]

Hello,
   
  when I search in a mailbox, for example for a particular sender, I  
sometimes get the message that an error has occurred during  
communication with the mail server and nobody is found.
   
  I use an older version of dbmail. In logfile is to read:
   
  WARN: HORDE [imp] [search] error when communicating with the mail  
server. [Pid 28046 on line 730 of "/www/htdocs/horde/imp/lib/Imap.php"]
