OpenSMTP / Dovecot Debugging
Hello,
after upgrading to OpenBSD 7.0 via sysupgrade(8), my clients (notebook and smartphone) can't connect to my mail server anymore. smtpd is running and so is dovecot. I checked my letsencrypt certificate and it is valid. In /var/log/maillog I can't find any clues ("info OpenSMTPD 7.0.0 starting" and some random connections - not my clients - failing with "smtp failed-command command="" result="550 no rDNS is so 80s""). I will try to connect to my server via OpenSSL to maybe get some hints but would be very grateful for ideas how to find out what's wrong. I set up the configuration on OpenBSD 6.9 following the awesome article by Gilles Chehade. Thank you very much! |

I just tried to connect via:
Code:
openssl s_client -showcerts -connect <name>:993 -servername <name> Code:
CONNECTED(00000005) write:errno=54 --- no peer certificate available --- No client certificate CA names sent --- SSL handshake has read 0 bytes and written 0 bytes --- New, (NONE), Cipher is (NONE) Secure Renegotiation IS NOT supported Compression: NONE Expansion: NONE No ALPN negotiated SSL-Session: Protocol : TLSv1.2 Cipher : 0000 Session-ID: Session-ID-ctx: Master-Key: Start Time: 1635498810 Timeout : 7200 (sec) Verify return code: 0 (ok) --- Code:
