I have an issue:when the email is sent from an address other than the authorization is required even if ip is on the same machine.

How can I avoid to make request authorization for a given ip ?

  • Postfix would do this with mynetworks. Sendmail has an equivalent setting, I guess. – Halfgaar Jul 3 '13 at 12:33
  • You should at least post relevant lines from the log file – adamo Jul 4 '13 at 6:58

Sendmail by default allows to relay from local IP addresses.

Have you used DontProbeInterfaces (confDONT_PROBE_INTERFACES) to change it too?
[Such change is quite common on virtual web servers with email served elsewhere ]

Do you use local IP addresses assigned after sendmail daemon startup?

  • In my sendmail.mc I have define(confDONT_PROBE_INTERFACES', True')dnl – famedoro Jul 5 '13 at 6:27
