If they are using DNS lookup and you don't have all the correct DNS info, they will bounce you. Do you have RDNS setup? What is the your email domain name?

Please retry or contact your administrator. <x.y.z.w #4.4.7> " This only happens to specific domains (but important ones to the company), email to other domains go out, and if I use my gmail I can send to the domains that my exchange can't send to. What could be the problem? tx -----Original Message----- From: Bob Fronk [mailto:bfronk@xxxxxxxxxxxxxxxx] Sent: Tue 12/14/2004 8:19 PM To: [ExchangeList] Cc: Subject: [exchangelist] RE: FW: The connection was dropped by the remote host http://www.MSExchange.org/ Sounds like you are black listed. What is your domain you are sending from?

Event viewer says: Message delivery to the remote domain 'mail.x.y.z' failed for the following reason: The connection was dropped by the remote host. tx ------------------------------------------------------ List Archives: http://www.webelists.com/cgi/lyris.pl?enter=exchangelist Exchange Newsletters: http://www.msexchange.org/pages/newsletter.asp Exchange FAQ: http://www.msexchange.org/pages/larticle.asp?type=FAQ ------------------------------------------------------ Other Internet Software Marketing Sites: World of Windows Networking: http://www.windowsnetworking.com Leading Network Software Directory: http://www.serverfiles.com No.1 ISA Server Resource Site: http://www.isaserver.org Windows Security Resource Site: http://www.windowsecurity.com/ Network Security Library: http://www.secinf.net/ Windows 2000/NT Fax Solutions: http://www.ntfaxfaq.com ------------------------------------------------------ You are currently subscribed to this MSEXchange.org Discussion List as: bfronk@xxxxxxxxxxxxxxxx To unsubscribe visit http://www.webelists.com/cgi/lyris.pl?enter=exchangelist Report abuse to listadmin@xxxxxxxxxxxxxx
