    Hello
    I have a latest 3.2.1 ispconfig (installed 3.2 beta and upgraded to release and then to 3.2.1). Postfix / dovecot on CentOS 8. Can't use SSL for POP3 and IMAP connections on Windows 7 clients's machines. SSL SMTP on 465 port works. There should be something simple tick in the config to support earlier clients...

    Did not found that in the forum archives, but I think it was discussed before, please help me to locate the info.

    Thanks.

    I'm sorry, I did not asked correctly. I know that there is a way to fix Windows 7 PC, but I'm looking for a some HOWTO where is written how to support an obsolete protocols needed for Windows 7 clients on the server.

    You can change
    Code:
    ssl_min_protocol = TLSv1.2
    to
    Code:
    ssl_min_protocol = TLSv1.0
    in /etc/dovecot/dovecot.conf. You might have to change the ciphers aswell - not sure.
