Hello. I have a problem with stunnel it does not connect to e-mail server. My situation. I have 2 servers: 1. Windows Server 2012 R2 STD. On it stunnel 5.55 is installed 2. Windows Server 2012 R2 STD. On it corporate MDaemon e-mail server is installed. Stunnel used to send e-mail from server 1 to server 2. Every worked fine... 2 days ago an SSL-certificate on e-mail server was renewed ( World CA, Sectigo). After it, new cert was installed on server 1, old cert was deleted - in Cerfificate store for Windows users - certmgr.msc. After it, stunnel saw only old cert, not new. I reinstalled it, copied settings for my e-mail server from old stunnel.conf to new. And now - stunnel does not connect to e-mail server at all. In writes:
2019.10.15 17:39:37 LOG7[6]: TLS state (connect): before SSL initialization 2019.10.15 17:39:37 LOG7[6]: TLS state (connect): SSLv3/TLS write client hello 2019.10.15 17:39:37 LOG3[6]: SSL_connect: Peer suddenly disconnected 2019.10.15 17:39:37 LOG5[6]: Connection reset: 0 byte(s) sent to TLS, 0 byte(s) sent to socket In the attachment stunnel.conf and log ( with debug = 7 ) for stunnel. Settings for e-mail server in [kvarta-mail] section. I spent 2 days. I read manual, Google, tried some methods - but nothing... If you hope me, i'll be very happy. Thank you. -- Рагиня Александр
