Connections/contacts with the comcastbiz postmaster?

[LER]

anyone here have contacts or connections with the comcastbiz postmaster(Email folks)?

I can't send mail to a client of mine since their server doesn't seem to be able to look up my reverse DNS. Everyone else can.

Thanks!

seems my problem was related to my OLD colo provider re-announcing my IP block.

Once that was fixed, my issue went away.

Closing.
