Description

When trying to send email on job failure I get:

login() got some positional-only arguments passed as keyword arguments: 'username, password'

Looking at the yacron code it looks like keyword args are used:

This wasn't an issue for me until recently so some dependency perhaps moved and started to trigger this?

Pinning aiosmtplib==2.0.2 solves the issue for me. Something in my environment must have bumped to a v3 version of that dependency.
