Some time today i started to have messages fail. We have looked into it and think we are black listed somewhere. It's smtp messages that are not going thru to vtext, att, sprint, uscc and maybe more. Right now the work around is a new carrier that directs it thru exchange server and use that as a failover for the SMTP carriers. Any other reports on this?

What are the chances that those carriers use the same black list?

Tim.

Tim,

There is a connection test we need to run that requires the Telnet Client to be enabled in Windows.

If you use Windows XP or Server 2003, the Telnet Client is enabled by default.

If you use Windows Vista, 7, 8/8.1, Server 2008 or Server 2012, you will need to enable the Telnet Client.

Here's how to enable the Telnet Client in Windows Vista, 7 or Windows 8/8.1:

1) In Windows, open the Control Panel.

2) In the upper right hand portion of the Control Panel, set “View by” to Small Icons.

3) In the Control Panel, open Programs and Features.

4) On the left hand side, click on "Turn Windows Features on/off"

5) Put a check next to Telnet Client.

6) Click on OK.

Here's how to enable the Telnet Client in Server 2008 or Server 2012:

1) In Windows, open the Server Manager.

2) On the left hand side, click on Features.

3) On the right hand side, click on Add Feature.

4) In the Features list, put a check next to Telnet Client.

5) Click on Next.

6) Click on Install.

After the telnet client has been enabled, this is the port test you'll want to run:

1) In Windows, run a Command Prompt.

2) In the Command Prompt, type the following and hit enter:

telnet smtp-bb.vtext.com 25

What response did you receive to that command?

If port 25 is open but there is an outstanding issue with the public IP the system sits behind, you'll receive a 554 or a 421 rejection notice.

This response indicates that your public IP is on a blacklist, so you will need to determine which blacklists you're on. To do that, from the computer running the software, go to www.whatismyipaddress.com and get your public IP.

Then click on the Blacklist Check option at the top of the page and run the test. Any list that has a red ! next to it is a list the IP address is on, so you'll want to go to each of those links and go through their provided lookup and removal steps. Once your IP is off of those blacklists, you can use direct SMTP from that system once more.

Tim - remember when we discussed adding the cellular modem to your PageGate? The issues with SMTP and blacklisting is one of the primary reasons. It also ensures that your messages get out in the event your internet connection or mail-server is down
