I had disabled SSL/TLS for all accounts, but not STARTTLS for outgoing SMTP server. I tried disabling this now, with no luck. (Should I delete all SSL accounts under mail shield / expert settings and rebooot?)
I really appreciate your help! Sorry if I am not being clear. I have not touched any of these settings, and everything has been working until now.
My e-mail provider is broadpark.no (NextGenTel).
