From my mac mail client I've connected to remote exim+dovecot server. Since few weeks back I was not able to send mail but able to receive.

Is it the problem with dovecot or exim?
Should exim contact dovecot prior to sending the mail?
I have also tried windows mail client with same error.
driver = pam
args = %s
driver = passwd
args = blocking=no
