Problems after changing internet providers

[ECCCTECHCOORD]

After switching to a new internet provider we started having problems with messages sent to Sprint. Some go some don't and most all of them take longer. I noticed today in the logs that messages are now trying to connect to our mail server but I don't see where they did that before the changes in our internet provider which meant also changing MX records and PTR records. Below is a log of a message sent before the internet change and one for a message sent after the change.

[Tech Support]

Thanks for posting the logs. Based on what we can see in them, it looks like the direct connection requests are failing, as noted in this section of the log:

10/22/2015 1:59:47 AM spmail-sms-gw-nj.cloudmark.com
10/22/2015 1:59:47 AM Trying host: spmail-sms-gw.cloudmark.com
10/22/2015 2:00:03 AM Trying host: spmail-sms-gw-nj.cloudmark.com
10/22/2015 2:00:18 AM Trying host: mail.hrecc.org

Unlike the 9/20 connection, the system can't make a connection with spmail-sms-gw-nj.cloudmark.com, so it's failing over to your mail server mail.hrecc.org

If you would, to confirm the issue, please run this test:

1) In Windows, run a Command Prompt.

2) In the Command Prompt, type the following and hit enter:
telnet spmail-sms-gw-nj.cloudmark.com 25

Please let us know what the response is.

It looks like they don't trust or know our new IP. I will visit the website noted and see if I can get that changed.
