Is it me or is it Delta? Adventures in IMF and Exchange.

I had problems with ISA and Delta's website. Problem went away when I removed ISA.

IMF is wacking Delta email reservation confirmation emails when set at 7. Delta goes through with a lot of porn spam when set at 8.

I looked up all the Delta email servers listed using dnsstuff.com. I add all those ips as allowed ips. Exchange System Manager/Global Settings/Message Deleivery/Connection Filter/Global Accept and Deny List Configuration/Add.

I get an email from my account that reservations from Delta are getting blocked again.

I open my spam manager, IMFFilterManager and I note the sending ip. It is an ip not listed in their mx records. I add that ip.

Rant: If they run their business the same way they run their IT then no wonder bankruptcy is lurking. Never mind, I already have heard how management has driven the company to the position they are in.

If I am doing something wrong let me know but I would hope that I am doing this allow email from an ip correctly.
