Postfix and SASL2 authentication

[Sunil Sunder Raj]

Hi,
Enable verbose logging so that you get readable error messages.

8) ee /usr/local/etc/postfix/master.cf
search for smtpd and append -v.
When your done it should look like this:
# ==========================================================================
# service type  private unpriv  chroot  wakeup  maxproc command + args
#               (yes)   (yes)   (yes)   (never) (50)
# ==========================================================================
smtp      inet  n       -       n       -       -       smtpd -v

restart postfix. Without properlogs you cannot cometo a conclusion.

Regards
SSR
