...Ubuntu version, it may (most likely) be necessary to enable TLS 1.0 / 1.1 in openssl as well. I ran into this with Debian 10 some time ago. /etc/ssl/openssl.conf [system_default_sect] -MinProtocol = TLSv1.2 +MinProtocol = TLSv1 In terms of Dovecot ciphers config, Windows should be happy with TLS_RSA_WITH_3DES_EDE_CBC_SHA which is less broken than the other older ciphers. -- K -------------- next part -------------- An HTML attachment was scrubbed...

Hello, I came across a strange problem with my Dovecot 2.1.7 installation (updated Debian Wheezy) in regards to SSL/TLS connections. My configuration is as follows: $ dovecot -n | grep ssl service imap-login { ssl = yes ... } ssl_cert = <...... ssl_cipher_list =

I currently use Ubuntu 20.04 with Dovecot 2.3.7.2 and OpenSSL 1.1.1f. A few months ago there was an update to all these systems and since then I've had to talk W7 and old Mac clients through disabling ports 993/995 with TLS enabled back to ports 143/110 without SSL or they could not pick up email.
