Dovecot 2.3-rc1 SMTP submission proxy always gives TLS required error even when already using TLS
First of all, I apologize for my accidental empty message earlier.
I just set up the SMTP submission proxy in Dovecot 2.3, but whenever I try to connect to it, it always returns "530 5.7.0 TLS required." for any sort of AUTH or MAIL command. This occurs even if TLS is being used. It also occurs regardless of whether I connect with a real client (Thunderbird) or manually with openssl s_client and regardless of whether a loopback connection or a remote connection is used. Here is the output of "dovecot -n". Please let me know if I can provide any other data. Thanks!

Confirmed. Working on a fix.

I can confirm that it works correctly in 2.3.0, thanks!

I think I spoke too soon. It works correctly (requiring TLS but working once STARTTLS has been done) for remote connections, but it also is requiring TLS for loopback connections, even though the rest of Dovecot doesn't work this way.

Ok, confirmed.
Fix is pending.
