|a couple of days ago I upgraded our server from Ubuntu 18.04 to 20.04,
thereby upgrading dovecot from 2.2.x to 2.3.x.
|Since then, some older versions of apple's mail.app (bundled with el
Capitano, released in 2016) no longer connect. When I turn on SSL
debugging, I see:|
|Debug: SSL error: SSL_accept() failed: error:14209102:SSL
imap-login: Debug: SSL error: SSL_accept() syscall failed: Invalid argument|
|Unfortunately, it doesn't reveal the name of the unsupported protocol.
Also, what about the failed syscall? Does dovecot try and fail to open
|Here are the contents of /etc/dovecot/conf.d/10-ssl.conf:|
| ssl = yes
ssl_cert = </etc/ssl/letsencrypt/idaweb-mail.rooot.de/fullchain.pem
ssl_key = </etc/ssl/letsencrypt/idaweb-mail.rooot.de/key.pem
ssl_ca = </etc/ssl/letsencrypt/idaweb-mail.rooot.de/ca.pem
ssl_client_ca_dir = /etc/ssl/certs
ssl_dh = </etc/dovecot/dh.pem
|I would greatly appreciate any hints!
