[Dovecot] More logging for Deliver (eg file name)

Hello,

I can't see from the wiki if it's possible to log extra information with Deliver - such as the file name it's using to save the message in (Maildir).

Currently I get the date, address, ID and folder, eg:

Dec 09 12:07:06 deliver(my_address@invalid): Info: msgid=302ce8b50912090406y634d1340j96ebd54466a2d08b@mail.gmail.com: saved mail to INBOX.Lists.centos

Thanks.
