Question : Recipient address rejected: Greylisted for 5 minutes Event id: 7002

Hi

A SBS 2003 R2 all SPs installed. One nick. External spam filtering company filters mails and in the HW FW I accept smtp only from their IPs. Due to Open Relay the email domain were blacklisted at Barracuda and Tiopan but hopefully anymore. I just disabled "Connection Filtering / Block List Service Configuration" three clacklist servers I had there.

IPs and email addresses below are slighty modified.

The IP 89.166.51.xx should not have anything to our mail system. It is rather the recipients mail server address.

I got these warmings: This spesific firstaname.lastaname@blueoranges.fi appears there 6 times at one minute Interval. Anything I can do?

Thanks,

Juha

I don't know for what reason today it works. Maybe shutting down the computer did the trick!.
