Just want to mention to anybody else who finds this thread.

I’m running an smtp server on my network that I’m pointing home assistant at. I had it working, then it stopped working at some point recently. The notify service would appear only if I put in an invalid IP address. I had to set verify_ssl to false in my configuration. I’m guessing a recent update changed the default value.

THANK YOU DAVID!!! THIS WAS IT!!! Created an account just to tell you adding that line completely fixed my issue. What a pita!

David, thanks for that update. Some recent update (or maybe in the last couple of years) broke my email notifications, and the verify_ssl: false addition to my smtp config fixed the sending issue. In the logs it would show that the notify.email service wasn’t available, and your line fixed the issue.

Thanks again!

P.S. I am running my own local email server, which might have something to do with why it’s now required. I use self signed ssl certs.

I have the same problem and errors:

During handling of the above exception, another exception occurred:

I also wanted to notify anyone having problems with SMTP not working to try setting encryption: none in case you are using an SMTP server without encryption (e.g. an old fashioned SMTP server listening on port 25 with no starttls).
This wasn’t mentioned in the documentation and I thought that the encryption line would only be needed if using starttls, but after tweaking for some time I tried setting encryption: none and that’s when it started working.

Edit: When actually reading through the documentation I found that my comment above, regarding the documentation, is false. The encryption variable is indeed documented in the documentation and it clearly states it is an optional variable which defaults to starttls. This explains why I had to explicitly declare the variable as none in the config. I’ll leave this comment here, however, in case someone else runs into this same problem.
