do you have any domain blocker in place. make sure the websites are allowed to send/receive from there.

also, if you are having issues then it could be the sender has got some issues, get them to check for issues at their end such as RBL, SPAM databases etc.

Do a check to make sure the domains aren't RBL'ed here:
