Jeff, here is the result of the ping from my blueonyx box

[root at ns1 ~]# ping -M do -s 1464 smtp.mm.gmexico.com

PING smtp.mm.gmexico.com (187.174.140.198) 1464(1492) bytes of data.

My conclusion is that the remote server is blocking de incoming ICMP so
there is no way we can retrive the mail from this server.

I just talk to the other side to find out a solution.

I will keep the progress.

Again Thanks for your help
