Yes the Exchange server is a SNAT client and there is no error appearing at the client as I can send mail fine. The problem is on the external side and getting the ISA server to receive the mail on a different port and then publishing it to exchange on the specified port. I used gmail to try and send test mail to my published server. It receives the mail delivery error. thanks On Sat, 30 Oct 2004 07:21:54 -0700, Jim Harrison <jim@xxxxxxxxxxxx> wrote: > http://www.ISAserver.org > > Is the Exch server a SecureNAT client? > What is the error seen at the client? > What is in the ISA logs for those requests? > What are you using to test the connection with; mail client, telnet, > WinsockTool? > > Jim Harrison > MCP(NT4, W2K), A+, Network+, PCG > http://isaserver.org/Jim_Harrison/ > http://isatools.org > Read the help / books / articles! > > -----Original Message----- > From: Marvin Cummings [mailto:MarvinC@xxxxxxxxx] > Sent: Friday, October 29, 2004 4:43 PM > To: [ISAserver.org Discussion List] > Subject: [isalist] Problem publishing port > > http://www.ISAserver.org > > I'm having trouble configuring ISA to map port 26 to my Exchange > server.
