Hi,
Sending Exchange config:
SBS 2003 current patches & service packs
Client - Outlook 2007
Receiving Exchange config:
SBS2003 R2 - current patches & service packs
I'm a little stumped here. I've got a situation where I get an NDR with a
5.5.0 error: user unknown when sending to one of our clients. However, I
CAN send a message to that same domain via telnet using the same 'Mail From'
address. Initially, I had assumed this was related to an reverse DNS/SPF
issue but the settings for my end seem to be fine; I then added a custom
rule on their Ninja spam filter for our domain, but that wasn't it either.
Any suggestions on what I'm missing here?
The message header on the NDR:
