GMail email issues in TrueNAS 12.0 (Connection reset by peer)

[vpv]

Hi!

I've been running TrueNAS 12 for a while at home and decided to set up email notifications. Using GMail does not seem to work. The test emails are sent, but the daily email, which might be about scrub tasks, always fails.

/var/log/maillog has these in it:

Code:

Jan  5 03:45:00 truenas 1 2021-01-05T03:45:00.599690+02:00 truenas.local /middlewared 188 - - Failed to send email to myemail+truenas@gmail.com: [Errno 54] Connection reset by peer

I'm using GMail OAuth. The first test email always succeeds, the later emails fail. Any ideas? Should I post a Jira ticket?

myemail+truenas@gmail.com

did you edit this, or is that how it is in the log?

I edited it to hide my real address.

I found Python exceptions related to this from /var/log/middlewared.log.

There's more, but I think that's the most relevant part.

After a bit of Googling I found this https://stackoverflow.com/questions/48019198/brokenpipeerror-when-using-gmail-api which then led me here https://github.com/googleapis/google-api-python-client/issues/218

Seems to me like an unsolved issue in the Google Python libraries.

I would ask that you report your findings to the bug tracker here: https://jira.ixsystems.com/projects

The development team may be able to find a work around.

I finally had the time to make the report: https://jira.ixsystems.com/browse/NAS-108932
