The 0.02/0/0/50 means that Postfix spends 50s waiting for DOVECOT
to accept the mail.
Look in your DOVECOT logs for warnings or errors.
The format of the "delays=a/b/c/d" logging is as follows:
a = time from message arrival to last active queue entry
b = time from last active queue entry to connection setup
c = time in connection setup, including DNS, EHLO and STARTTLS
d = time in message transmission
