I'm not sure if there is a problem with the mx records. We did have a problem a couple of months ago and had to have the isp add a ptr record. -----Original Message----- From: John Mason [mailto:John.Mason.Jr@xxxxxxxxxxxxxxxxx] Sent: Monday, April 05, 2004 12:24 PM To: [ExchangeList] Subject: [exchangelist] RE: smtp;521 Server does not accept mail http://www.MSExchange.org/ Is there a problem with the published MX records for your domain? Do you have any blocked IPs on exchange or your firewall? -----Original Message----- From: seabass [mailto:denisedorrance@xxxxxxxxxxx] Sent: Monday, April 05, 2004 12:17 PM To: [ExchangeList] Subject: [exchangelist] smtp;521 Server does not accept mail http://www.MSExchange.org/ Can anyone tell me what this means? smtp;521 Server does not accept mail. I am running NT 4 sp6a, Exchange 5.5 sp4? I can send and receive emails but others are telling me there are problems. The problem is with outside users sending to us.
