It superficially looks like smtplib is messing up from sleuthing around the stack trace. I probably don't understand how the encoding supposed to work though, because it looks like they just up and call .encode('ascii') right at the beginning of their sendmail method. I don't understand why I see other examples of smtplib usage working similarly. I do see that yagmail is passing a 'utf-8' encoding to MimeText and classes like that in prepare_message.
I also don't see a lot of other complaints about this here (not since 2017) so it's probably my environment. Python 3.7.3. yagmail==0.11.220. MacOS Sierra, but also possibly happening in an Ubuntu Linux server environment.
I haven't been able to reproduce the issue yet with my contents, when using yagmail on its own--only in the context of my application being run (definitely environmental)... Could use a suggestion on what to look into.
