I have applied this patch to 1 server, and it's logging away. Let me know what kind of output you'd like to see. Or i can send you the raw logfile.  As I said previously, im not longer running the imap server=0 patch because it caused these errors:

Dec  9 06:54:32 userimap30 dovecot: imap(cor): Error: user cor: Initialization failed: Namespace '': mkdir(/var/spool/mail/.4a/L/0/14/corbosch) failed: Permission denied (euid=1000(cor) egid=50(staff) missing +w perm: /var/spool/mail/.4a/L/0/14, euid is not dir owner).  

After I removed the patch these errors disappeared.
