SMTP IP Relay log

Question

I have a IIS SMTP Relay question and need some help. I have recently added a new Allowed IP in the relay restrictions. The mails are sending through but there is no log on the IP. The old Allowed IPs are still logging. Is it because the destination server is under the same subnet of the new Allowed IP? I would like to keep a log of the email sent for record. Also tried to uncheck "Attempt direct delivery before sending to smart host" and its still not logging. Help would be much appreciated.

Answer 1

Hi,

I know little about IIS SMTP relay so my suggestion might not help.

We can compare values of new and old allowed IPs set in step5 and step6 of How to: Setup A SMTP Relay In Windows 2012 R2 – IIS 6. Or we can increase values set in step6. Maybe the limit is not big enough to log new allowed IPs.

I don't understand what's the meaning of step8 but please

set all the devices that need SMTP relay to point to the new SMTP server you just setup and test
