There is situations when more than one socket is needed: for chrooted 
processes.

About year ago I did a lots of tests with different chroot setups 
(internal chroot/external chrooting).  About 10 bugs in dovecot was 
discovered... most of of them are fixed now. [see old post by me; thanks 
Timo:))] But final conclusion was - Dovecot currently isn't designed for 
use in chroot setups. Also "mail_chroot": setting brings up more 
problems than benefits (unable to use external binaries (sendmail) for 
bounce messages, plugins don't work as expected etc.).
