Intermittent Scan to email funcitonality
-
The router does have a rule to block SMTP unless it is bound for 10.202.1.14
I can watch the allow stats increment when I send a successful email from the NAS and on the rare times that the HP sends. But when the HP fails, the Deny rule does not change. It is not being hit.
-
For troubleshooting, I also created an new allow rule on the Windows firewall of the exchange server. Again should not be relevant because the NAS works, but still.
Not showing each tab, but basically allow all port 25 from any remote IP to any local IP.
-
The receive connectors allow the entire remote subnet at the moment. I originally had it set to the various printer's specific IP.
I move the networks between auth and anon as needed when testing.

Ok, I am thinking that you need to see if there is a firmware update for the printers. Can you get us the firmware it's on, and we'll see if it's on the latest version? Maybe it's a bug that got worked out.

All printers are now on current firmware as of last week. HP support already went down that route. Sorry for not mentioning that already. They were only one rev behind anyway.

Hmmm....I can't remember. Did you run a continuous ping test against it when you were testing SMTP? Could you have some bad JetDirect cards?
-
Yes, I had a ping 10.202.10.20 -t running from the mail server for the last 5 days.

@Dashrender asked earlier about them being on the same switch. Could there be a middleman networking device killing the connection somewhere? An L3 switch or something similar?

The conneciton from the main office to the branch offices are all OpenVPN site to site tunnels using Ubiquiti EdgeMax LITE routers. Everything has worked fine for 2 years. Suddenly a week and a half ago, we started having problems.

So these are plugged directly into the router?

They are plugged into an HP 1910-24 PoE switch at their respective branch office
Printing works fine. Scan to network folder works fine. Email works sometimes. -
Just setup an old MFP at one of the offices. It sent emails without error.

It sounds like a permissions issue, of some sort, to me. With what I know now, it's something on Exchange doing this. I'm just not familiar enough with Exchange on-premise to be of much use there.
-
Can you post a screenshot of the HP's SMTP settings?
-
We haven't seen that yet, so that'd be helpful.
-
Some HP printers print through an HP service.. any chance that's the case here, it's not actually sending email directly from the device, but instead it's coming through HP's cloud? and there might be a problem there?

I hadn't thought of that. That's a very good idea.

I always use authentication for all devices unless I absolutely have to do anon. As a test I tried anon and it would also still fail. Switching back and forth did not make it work. It works intermittently on both methods.

As requested obviously I use a real email before I click test.
