Hi, my email server can send emails to outside world but cannot receive email from outside. For example mail sent from Gmail or hotmail gets delayed for hours and later bounce back with 'unknown destination' error code or something to that effect. My email server sends mail through proxy/NAT interface. Mail is relayed through my ISP provider's smtp.xyz.com mailservers. I have DNS service provider with easydns.com. Any clue as to what am missing out? Thanks -- redhat-list mailing list unsubscribe mailto:redhat-list-request@xxxxxxxxxx?subject=unsubscribe https://www.redhat.com/mailman/listinfo/redhat-list
