It's possible, you need to adjust the IMAP & POP3 logging configuration, 
then parse the mail log and collect in/out values. E.g.:

doveconf -a | egrep '(imap|pop3).*logout_format'
imap_logout_format = rcvd=%i, sent=%o
imap_urlauth_logout_format = in=%i out=%o
pop3_logout_format = rcvd=%i, sent=%o, top=%t/%p, retr=%r/%b, del=%d/%m, 
size=%s

egrep 'dovecot: service=imap, user=user at domain.com.au.*Logged out' 
/var/log/maillog | tail -n 1
Jul 20 15:59:38 server dovecot: service=imap, user=user at domain.com.au, 
ip=[127.0.0.1]. Logged out rcvd=38, sent=593

YMMV
