Over the weekend I updated a few packages on my system. Full list below. This morning one of my users who is using Thunderbird on an ancient Windows box reported to me that they can't check email anymore. They can get to the web page for my mail server, so it isn't network connectivity. Nobody else has reported a problem. My first thought was that the update changed the available TLS versions and his old box can't connect anymore, but the dovecot configs haven't changed. Has anyone else experienced anything similar?
While fail2ban is installed, it isn't configured or running. I also checked that. :) -Chris ---> Package autorespond.x86_64 0:2.0.5-0.qt.el7 will be updated ---> Package autorespond.x86_64 0:2.0.5-1.qt.el7 will be an update ---> Package certbot.noarch 0:1.5.0-1.el7 will be updated ---> Package certbot.noarch 0:1.6.0-1.el7 will be an update ---> Package dbus.x86_64 1:1.10.24-13.el7_6 will be updated ---> Package dbus.x86_64 1:1.10.24-14.el7_8 will be an update ---> Package dbus-libs.x86_64 1:1.10.24-13.el7_6 will be updated ---> Package dbus-libs.x86_64 1:1.10.24-14.el7_8 will be an update ---> Package fail2ban.noarch 0:0.10.5-2.el7 will be updated ---> Package fail2ban.noarch 0:0.11.1-9.el7.2 will be an update ---> Package fail2ban-firewalld.noarch 0:0.10.5-2.el7 will be updated ---> Package fail2ban-firewalld.noarch 0:0.11.1-9.el7.2 will be an update ---> Package fail2ban-sendmail.noarch 0:0.10.5-2.el7 will be updated ---> Package fail2ban-sendmail.noarch 0:0.11.1-9.el7.2 will be an update ---> Package fail2ban-server.noarch 0:0.10.5-2.el7 will be updated ---> Package fail2ban-server.noarch 0:0.11.1-9.el7.2 will be an update ---> Package kernel.x86_64 0:3.10.0-1127.18.2.el7 will be installed ---> Package kernel-headers.x86_64 0:3.10.0-1127.13.1.el7 will be updated ---> Package kernel-headers.x86_64 0:3.10.0-1127.18.2.el7 will be an update ---> Package kernel-tools.x86_64 0:3.10.0-1127.13.1.el7 will be updated ---> Package kernel-tools.x86_64 0:3.10.0-1127.18.2.el7 will be an update ---> Package kernel-tools-libs.x86_64 0:3.10.0-1127.13.1.el7 will be updated ---> Package kernel-tools-libs.x86_64 0:3.10.0-1127.18.2.el7 will be an update ---> Package python-perf.x86_64 0:3.10.0-1127.13.1.el7 will be updated ---> Package python-perf.x86_64 0:3.10.0-1127.18.2.el7 will be an update ---> Package python2-acme.noarch 0:1.5.0-1.el7 will be updated ---> Package python2-acme.noarch 0:1.6.0-1.el7 will be an update ---> Package python2-certbot.noarch 0:1.5.0-1.el7 will be updated ---> Package python2-certbot.noarch 0:1.6.0-1.el7 will be an update ---> Package qmail.x86_64 0:1.03-3.qt.el7 will be updated ---> Package qmail.x86_64 0:1.03-3.2.qt.el7 will be an update ---> Package qmailadmin.x86_64 0:1.2.16-2.qt.el7 will be updated ---> Package qmailadmin.x86_64 0:1.2.16-3.2.qt.el7 will be an update ---> Package spamassassin.x86_64 0:3.4.1-1.qt.el7 will be updated ---> Package spamassassin.x86_64 0:3.4.2-2.qt.el7 will be an update
