"Cc:" not being properly responded

Thanks for great work with davmail !

While trying to sort out the situation within company which decided to pursue path of Office365 I hit a roadblock which I can not figure out. When sending SEARCH command I am not getting proper response. Here is an example:

telnet 0 5143
Trying 0.0.0.0...
Connected to 0.
Escape character is '^]'.
* OK [CAPABILITY IMAP4REV1 AUTH=LOGIN MOVE SPECIAL-USE] IMAP4rev1 DavMail 5.2.0-2961 server ready
o login user@domain.com password
o OK Authenticated
o select inbox

* FLAGS (\Answered \Deleted \Draft \Flagged \Seen $Forwarded Junk)
* OK [PERMANENTFLAGS (\Answered \Deleted \Draft \Flagged \Seen $Forwarded Junk \*)]
o OK [READ-WRITE] select completed
o search 1:1779 CC "linux-users"
* SEARCH 800
* SEARCH 1080
* SEARCH 1276
o OK SEARCH completed
o search 1:1779 CC "linux-users@domain.com"
* SEARCH
o OK SEARCH completed

When I talk to Exchange web interface I am getting 3 results back. As you can see, issue is reproducible once '@' is in place. Also please note that this is not O365 interface, this is a in-house MS Exchange server.

Please let me know what additional details you will need.
