I constantly get this Error when trying to send Cold emails:
I'm sending emails through the listmonk App.
If I change the SMTP Settings to STARTTLS instead of SSL/TLS that I WANT to use it works fine and all emails are sent.
Any ideas?

@poisonbrain said in tls: the first record does not look like a TLS handshake:
If I change the SMTP Settings to STARTTLS instead of SSL/TLS that I WANT to use it works fine and all emails are sent.
That won't work. If you are using Cloudron Mail server to send emails, the internal connection is via SSL/TLS and not STARTTLS.
STARTTLS vs SSL/TLS shouldn't matter in the end. Why are you changing this?

@girish Not quite sure to be honest. I've only read that SSL/TLS is a better protocol than STARTTLS.
If I've understood correctly of course.Though I want my emails to be sent from Listmonk.
are these settings right ?because in the app this is chosen :
"Mail FROM Address
Use Cloudron Mail to send emails..... " while inside the listmonk domain the settings are these
