My generator sends out emails. It doesn't support encryption, just standard username/password authentication. I stopped getting emails a few months ago (it has worked for 7 years prior to this). I've tried 4 different SMTP servers and 3 different ISPs and no luck, so i figured it had to be something with the generator. So I setup Paperclip to find out why and wiresharked it. This was the captured file after the generator sent an email: https://drive.google.com/file/d/1A9ZeBTzxagtKYwP6effx4Lp6tajbYoTP/view?usp=sharing
The generator is .176, Paperclip is .39 Line 9 the generator sends the AUTH PLAIN command (with username 'generator', which is correct) and line 10 paperclip responds with 501 error and then the generator QUITs. I don't know how to fix this, I obviously can't change the generator email client, did something change in SMTP format recently where it stopped recognizing ESMTP commands like AUTH?
