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.
exim in /var/log/messages says:

(log is obfuscated)
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.
auth-system.conf.ext:
passdb {
driver = pam
args = %s
}
userdb {
driver = passwd
args = blocking=no
}
... Necktwi
