STARTTLS Issues #55

Open thebeline opened 3 years ago

thebeline commented 3 years ago

I am receiving a STARTTLS WRONG_VERSION_NUMBER error. My email server is used by a number of people, and many different application clients, without issue. I believe the problem here is related to Python 3.5, and this StackOverflow issue.

I don't know, however, as I have dug through the YagMail repo and found no mention of this issue (and I feel like it would show up). Any help would be fantastic.

Configured with my email domain, port 587 Use TLS/Use SSL, the correct username and password, and Thunderbird connects to the account just fine...
