Exchange 2010 email being lost to one external domain
Greetings.
I have an issue where my employees cannot send to a particular external domain. They receive an email from us on a rare occasion, but others never make it and we don't get any NDR or delay messages. I've tried doing read and delivery requests, but you can't expect much of those. I'm not having this with any other domain. The external domain says that they have added our domain to be safe and have added the IP address of our sending server. Neither party is on any blacklists. The attempted recipient states that they don't see any evidence within their AV (I think they said McAfee). Anyhow, I'm wondering if anyone knows of a site/tool that will allow me to track my outgoing emails? As I have to trust that the recipient's IT dept know what they are doing, I'm hoping to collect as much info as I can.
Any ideas?
Thanks,
Jeremy

Unfortunately, once there is a handoff from your organization to the recipient's, there isn't much insight to where the message goes or what happens to it.
But you can take the telnet info to them to show proof from your side.
Good luck and let us know what the outcome is.

Jer,
Will you provide a status update for us?

As expected, the issue was on the recipient's side. Apparently, 1 of our public IP addresses were being blocked their Barracuda solution. As such, this apparently blocked other IPs in the block. I never actually was able to get specifics. Since they 'corrected' the matter, our emails have flowed without issue.

Thanks for the feedback, guys. Sorry for being tardy on the closing of the ticket.
