I have a problem connecting my Exchange server to my ISP. My ISP can
now connect to my Exchange Server but it takes quite some time for
them to see my Port 25. If I telnet to the Exchange Server internally
it takes about 50 seconds for a response (which im told is far
excessive, internally it should be near instantaneous). Also I cannot
send extenal E-Mails, internal ok. All I get is the following:
Your message did not reach some or all of the intended recipients.
Sent: 06/01/99 14:51
The following recipient(s) could not be reached:
No transport provider was available for delivery to this
My questions are:
What reasons are there for a slow response from port 25, any settings
needed under control panel (NT4) TCP/IP, DNS etc.
Why can I not send external E-Mails, I can recieve external E-Mails.
Any help would be appreciated.
