That's the odd part. The server that's producing those errors CAN
resolve that host just fine. Note, that hostname has several round
robin IPs, except I have not been able to get the .73.26 one that you
came up with:
[1] 20:54:28 <kirash@ivanhoe:~> host alt4.gmail-smtp-in.l.google.com
alt4.gmail-smtp-in.l.google.com has address 173.194.67.27
[2] 20:54:30 <kirash@ivanhoe:~> host alt4.gmail-smtp-in.l.google.com
alt4.gmail-smtp-in.l.google.com has address 173.194.67.26
[3] 20:54:31 <kirash@ivanhoe:~> host alt4.gmail-smtp-in.l.google.com
alt4.gmail-smtp-in.l.google.com has address 173.194.66.26
