Hello,
I have ubuntu 22.04, dovecot 2.3.16 and old email client (Outlook 2013) and their dont support TLSv1_2.
In dovecot 10-ssl.conf i put: ssl_min_protocol = TLSv1,
in openssl.cnf i have:
openssl_conf = default_conf
[ default_conf ]
ssl_conf = ssl_section
[ssl_section]
system_default = ssl_default_sectq
[ssl_default_sect]
MinProtocol = TLSv1
CipherString = DEFAULT:@SECLEVEL=1

but when i check openssl s_client -connect localhost:993 -tls1_1
have output:

version tls1_2 and 1_3 works fine.
What I doing wrong?
Thanks for help.


Not to answer your question about TLS, but about Outlook. Your version of Outlook is outdated and seeing as you use Outlook with Dovecot, there is nothing special
that you need Outlook for. Why not just switch to something like Thunderbird for a MuA?
