MX Records Change

[Eric Leslie]

Mark:
Thank you for the reply. The MX record change occurred about two weeks ago.
Is there a way that I could ping for the availability of port 25 when I
connect back to the other ISP? Once I connect to the other provider, I am
able to connect to corp.metzgers.com and the IP address when using an
offsite computer. Problem being that I am trying to minimize downtime since
I do not control the DNS server, I can't control when the change occurs.

Any ideas on how to better accomplish what I am trying to do?

Eric

	This should have worked.

	I suspect that this is a timing issue in that the old MX
	RRset had not expired.  You did not say how long ago you made
	the change.

	Another thing it could be is that your new ISP is blocking
	incoming connections to port 25 or even that your new address
	is not being announced correctly.
