Hi! I went through most of the “SMTP problems” threads but still cannot solve my problem. Ubuntu in AWS EC2, fresh Discourse installation, can’t receive confirmation email. Current configuration: DISCOURSE_SMTP_ADDRESS: smtp.motomirko.pl DISCOURSE_SMTP_PORT: 465 DISCOURSE_SMTP_USER_NAME: admin@m…

Port 465 was, many years ago, SMTP over SSL/TLS – it doesn’t use STARTTLS. I say “was”, because it’s been deprecated for so many years that the IETF has deregistered smtps as a protocol. You should use either port 25 (SMTP) or port 587 (submission) and STARTTLS.

Yeah, you’re absolutely right, I moved from my old provier to gmail, and now everything works like a charm! Thanks!

Gmail is not recommended as it has limits for outbound mail. Check out MailGun - it is very straight forward to setup.

I hope it’s ok to bump instead of creating a new topic. My host only has smtps (465/ssl) available and I can’t seem to get it to work. DISCOURSE_SMTP_ADDRESS: mail.myprovider.com DISCOURSE_SMTP_PORT: 465 # smtps/ssl # DISCOURSE_SMTP_PORT: 587 DISCOURSE_SMTP_USER_NAME: login@mydomain.com D…

So my solution was first to switch to Gmail, but when google started making me problems (limits…) than i switched to MailGun like @ljpp suggested (thanks man it’s great!). I think that’s not possible to force discourse to use 465 anymore.

Thank you. I’ve signed up for SparkPost as I don’t want to change hosts for my mail. They give you 100 mails per day without verifying your mail, 500 if you do and 10.000 if you add your credit card details. Not too bad.
