imap(Port 143)＋STARTTLSでの設定
STARTTLS:暗号化されていない状態で通信を開始し、途中でSTARTTLSコマンドを実行することで通信経路を暗号化をする
# rpm -qa | grep dovecot dovecot-2.3.16-10.el9.x86_64
Postfix に SASL 機能が提供できるよう Dovecot を設定
# cd /etc/dovecot/

以下のようにすることでimps(Port993) SSL/TLS通信が出来るようだが、Thunderbirdが自己認証をサポートしないようなので、上記のSTARTTLSを検討する。
ssl = yes ssl_cert = </etc/pki/dovecot/certs/dovecot.pem ssl_key = </etc/pki/dovecot/private/dovecot.pem
service imap-login {
inet_listener imap {
#port = 143
}
inet_listener imaps {
#port = 993
#ssl = yes
port = 993
ssl = yes
}
# systemctl restart dovecot
# firewall-cmd --add-service=imaps --zone=public --permanent success # firewall-cmd --reload
imapを停止してimapsだけサービスを動作させることが出来ないのでfirewallでimapを切る
# firewall-cmd --remove-service=imap --zone=public --permanent success # firewall-cmd --reload success # firewall-cmd --list-services --zone=public cockpit dhcpv6-client imaps pop3 smtp ssh
