[Dovecot] Log imap commands

[forumer at smartmobili.com]

Hi,

I am trying to optimize an imap library and I am comparing with some 
existing webmail, for instance
from roundcube I can log the imap commands with the following format :

[11-Jan-2012 14:22:55 +0100]: [DBD1] S: * OK [CAPABILITY IMAP4rev1 
LITERAL+ SASL-IR LOGIN-REFERRALS ID ENABLE IDLE STARTTLS AUTH=PLAIN

...

And now I would like to do the same from my imap library so I have 
started wireshark but it's a bit messy and difficult to compare.
I was wondering if dovecot allows to log imap communications ?

Thanks
