your internal clients will not be able to connect ... in short any machine using the internal name for resoultion will not be able to connect. now you are asking specifically for mx records.... unless you have some subdomains configured and all that... basically when you send an email .. your mailserver gets in touch with the name server of the destination domain and asks for an mx record to find out who or which mail server is responsible for handling mails for that domain and based on that it then contacts the machien that is responsible for the mails and hands over the mails to that machine . so based on that you can make your own conclusions. -----Original Message----- From: mag@xxxxxxxxxx [mailto:mag@xxxxxxxxxx] Sent: Tuesday, February 26, 2002 12:33 PM To: [ExchangeList] Subject: [exchangelist] mx records http://www.MSExchange.org/ I have two exchange 2000 servers. One of them is on isa-server computer, and another - on internal computer. I think that there is a problem with mx records in my dns. What will happen if I remove mx record of internal computer? ------------------------------------------------------ You are currently subscribed to this MSExchange.org Discussion List as: syed.muqeem@xxxxxxxxxxxx To unsubscribe send a blank email to $subst('Email.Unsub')
