i am using dovecot version 1.2.11 with qmail toaster

is there a way to log the number of current imap connections at a given time using dovecot log format ?

No. With v2.0 you could get that easily with "doveadm who", but with v1.x you'd have to do a ps|grep imap$ or something. In both cases I'm not sure why you'd want it in dovecot log format..
