outbound whitelist

Post by dashandwerknet »

Hi,
i wanted to send to a domain, but the recipient never got this mail. After a look in the logfile i saw this :
421 4.7.1 not authorized !

I wondered, because i have no ip filter set.

Then i added the ip address of the reveiver domain to the smtp outbound whitelist and the mail was sent to the recipient without any error.

Where could i find the blocked sending address ?
I searched all of the smtp options, but nothing found.
