[Dovecot] Source patches from Apple

[Mike Abbott]

Hello Dovecot developers,

Apple has made and tested significant changes to Dovecot v1.1 and now  
is ready to contribute them back to your open source project.  The  
changes include:

Scalability and performance:
allow pop/imap mail processes to handle multiple clients
larger listen queues

Stability and maintenance:
fix to allow cross-compilation
workarounds for Mac OS X bugs
a couple general bug fixes
symbol conflict resolution

Features:
Open Directory integration
back off after failed auth attempts
Mac OS X-specific
handle dynamic host name changes

I could contribute these as one giant patch or as a sequence of  
discrete patches.  How would you prefer to receive them?
