Hi All,

We are hitting a bug with LAVA 2021.08: email notifications seem to be broken.

We believe this is due to a bug between eventlet 0.26.0 and dnspython.

Visibly, this is fixed in eventlet 0.32.0: https://github.com/eventlet/eventlet/issues/619

Did you face the same bug?

Any idea about how to fix that?

Thanks a lot,

Philippe
