Re: Mail from specific domain not received sbs 2003 -urgent-



Hi Charles,
Turns out the hosting ISP is the same as the senders'. The problem is with
the ISP. There were pop3 accounts active at the ISP's site. This resolved in
mail from same customers (domain 1: host ISP 1, domain 2: host ISP 1) was
delivered directly to the pop3 account. They are still busy disabeling the
pop3 accounts. We discovered this while sending an email to a non existing
recipient. This resulted in an NDR, from which we could trace the responing
mailserver. Instead of receiving an NDR from our SBS the sending user
received one from the ISP. At first he got an NDR telling the recipient is
unknown. Now however, he get's an NDR telling the
address is unroutable... Well we'll wait and see what the ISP is getting us
into next...
