Working with GetMail portion - have email addresses set on groups and users. This has been working flawlessly for years. We recently had one of our agencies change email domains. Prior was HARRISONCOES.COM - new one is HCESWV.COM. HCESWV.COM will not resolove any MX records in Pagegate. I've tried several DNS iterations, adding a zone locally, anything I could think of. When viewing logs, it starts the SMTP session, but DNS returns no MX records. Using tools like MXTOOLBOX on the pagegate machine DOES indeed return MX records. Any clue what I'm missing? I've been two weeks on this and making no progress.

Thanks.

Paul,

To dot a few i's and cross a few t's, if you open PG Admin and go to Interfaces - GetMail - Settings, what value is listed in the 'Local Domain' field?

Interesting... the MX record is certainly there and in place to redirect SMTP traffic to the 911page.net to the pg.911page.net mail handler. So, when something does an MX lookup on 911page.net, it knows it needs to connect to pg.911page.net (which is currently routed to the public IP 69.43.35.82).

If messages aren't coming in, it may be either a port blocking or port forwarding issue.

However, just to rule it out, let's first make sure the PageGate mail handler is present and ready for any incoming connections:

1) Open a Command Prompt

2) Type the following and hit enter:
telnet 127.0.0.1 25

Do you receive a 220 response or a 'could not open a connection' response?

It's outbound mail that's goobering....here's a log snippet.

Oh! Apologies, I thought it was the inbound email that wasn't working.

Based on what I can see in the log, it looks like the provided DNS servers can't do an MX lookup on the hceswv.com domain. For example this:

4/22/2019 12:00:00 PM > SMTP Delivery Session Started (To: alerts@hceswv.com) (Thread ID: 21)
4/22/2019 12:00:01 PM - MX host list received from 192.168.71.22 and 74.40.74.40 :

should have been followed up with an MX return of rx.citynet.net but instead, it came back with nothing.

Is the hceswv.com email domain technically internal to the network on which the PageGate server resides? If so, you may want to go to Interfaces - GetMail - Settings and update DNS Server 1 or 2 to reference an eternal DNS server (like Google's open DNS of 8.8.8.8 or 8.8.4.4) to see if that allow the MX lookup to complete.

Let me further muddy the water....when I added the MX records to the local DNS server, it worked exactly ONCE - received MX records in PageGate, sent the message. All subsequent attempts get no MX records. Runs in my mind that's exactly what happened the first time I changed it a couple weeks back, using standard external DNS servers. Some garbage queuing somewhere?

...and I've done the MX checks from the pagegate machine - and they work.

It's an external domain - Google hosted even.

There's a test I'd like you to run, please.

Create a test recipient set to use one of your SMTP carriers and use alerts@hceswv.com in the ID/PIN/Email field.

Then try to send that recipient a message and post the connector log of the connection attempt.

Tried it a second time - still worked. And it's getting the MX records from the local DNS server, because it's only two returned....that's all I entered locally.

If you would, open PG Admin and go to Logging - Settings, then set the logging level to Debug and click Apply.

After doing that, re-run the same test and post the more detailed log, there are a few things we'd like to cross-reference.
