Description

A Traceback is generated if Internet Access is not available when routine mails are due to be sent.
Would it not be better to log an error message rather than a traceback ?

Traceback (most recent call last):

    server = _get_smtp_server(timeout, local_hostname=local_hostname)

#5 Updated by Dru Lavigne over 3 years ago

To clarify: you still get the traceback on U1?

#6 Updated by Alec Pearson over 3 years ago

I have not tried to break it.
The mails go out at 0300 and it just happened that the VPN went down that night.
Let me give it a go.....

This is the traceback on FreeNAS-11.0-U1 (aa82cc58d)
I can now see that there is an error messaged generated but the Traceback is what catches the eye.....

The traceback is part of the error message that is logged:

log.warn('Failed to send email: %s', errmsg, exc_info=True)

This is Behaves Correctly.

I beg to differ, IMO tracebacks should only be recorded to the specific facility and when it makes sense to have one.

#12 Updated by Sean Fagan over 3 years ago

Then get rid of the exc_info=True, and it's done I guess.

I, personally, want to know where and why it failed, but I'm not the normal user, so...

I was able to send a test email to an email ID, but I do not know how to test it without internet since it is a VM on techvcenter. I will detach the NIC tonight for the VM and test it when it tries to send at 3:00AM.

After searching for Tracebacks in /var/log/debug.log , I found two traceback errors which was not related to email as shown in the attached image, which was not related to routine email. Test Pass
