DB Errors [SOLVED]

[Daniel Hazelbaker]

It indeed does NOT include that patch.  It includes the cyrus- 
imapd-2.2.7-autocreate-0.2.diff patch, which does not perform the  
NULL checking on rcpt_userid.  So it seems to be an oversight on  
YDL's part of not including the latest patch.  I'll drop them a line  
letting them know, but I have had no problems with my solution so I  
think I am okay.
