Summary:                    Lags when using imap
Description: 
I'm using asterisk version 1.4.26 and 1.4.29 with imap client UW 2007e. On
my exchange server I've created a superuser account, and try to connect to
it through login Donain\superuser\user. From tcp dump I see, that
authentication goes well, but asterisk and exchange server begins to lag:
unable to call another phones or voicemail, and whery hard to send email
through exchange server. CLI of asterisk also lags: show of debug and
verbosity practicaly stops, and another features don't work or work very
slow.

Seem's that problem is in search procedure. When Imap client sends request
to search for undeleted seen messages with header (X-Aster-Exten and
X-Aster-Context) for some mailboxes it takes about 60 seconds to recieve an
answer. I'd optimised the search (not searching for headers Exten and
Context but for header from whom was recieved this letter). Seems that this
can help to reduce searching time. But I couldn't check it because I've run
into another problem. Another solution is to create a special folder in
every mail box for voicemail letters, but my leaders want to use this
alternative last off all.

Our company has about 20 employee. For mailbox with 100 letters it takes
about 60 seconds to recieve response. 
Still working on virtual machines, with version 1.4.26 trunk
