The email log file should be in the mxdiags folder - smtp.log

I am running mono 6.12.0.182 and just tested it again on my rPi 4 and the email was sent OK

I can confirm there's an issue.

Trying on one of the systems (GW2001) I sent an alarm test email (via outlook.com) and the pop up on the dashboard came back with :

Test email failed: Object reference not set to an instance of an object.

And the log file has

2022-09-03 17:33:07.780 Sending test email...
2022-09-03 17:33:07.782 Object reference not set to an instance of an object.


but it does keep on working!

Yes, I upgraded to mono 6.12.0.182 and the mail is now received. No crash. So: problem solved.

But now I can't send files - FTPS - from my CumulusUtils anymore
I am seriously beginning to dislike some libraries and mono.

So I bit the bullet and did it on my main system (WH65) and that crashed.

The log file simply had

2022-09-03 17:53:19.710 Sending test email...
2022-09-03 17:53:19.726 SendEmail: Sending Test email, to [xxxxx1@outlook.com], subject [Cumulus MX Test Email], body [A test email from Cumulus MX.]...


blanked out my email address - I have several!

That was all - no other information Console logs looked ok BUT the ServiceConsoleLog-Old.txt was not at the correct time/date - it looks like it crashed before writing the old log. Also although I had set the log SMTP flag - no log was produced.

Both systems (GW2011 and WH65) are running on the same RPi 4 Bullseye, Mono version: 6.8.0.105 (Debian 6.8.0.105+dfsg-3.2 Mon Jul 12 07:04:24 UTC 2021)

It is the mono version @Phil.

Apparently 6.12 has become a prerequisite for CMX.
I think that must be communicated as such.

Can confirm Hans' finding - latest stable Mono allows emails to be sent.

Oh.... and ignore the error on GW2001 - I hadn't set up the SMTP info - I have now and it is working also

Yes mono is becoming an increasing pain, especially as people are shifting focus to .Net 5 & 6 and abandoning Framework.

I've added a note to the release announcement.

Now we have this resolved, I will release a patch for the other issues in 3.21.0 tomorrow...

I'm running bullseye on my RPI 4 with mono 6.8.0.105 Sending test email OK

Cumulus MX v.3.21.1 build 3205

3204 was OK as well

Same here - but I upgraded to 6.12 without testing whether 6.8 worked!

I think it will depend on the encryption algorithm your provider wants to negotiate. The newer algorithms needing the latest version of mono.

OK
I wasn't telling the full trues exim4 on cmx RPI with dc_smarthost=<postfix server>
