We finally solved the problem. For some reason dovecot stopped accepting mail.sgeinc.com but wanted sge.sgeing.com, the real name of the machine, not an alias name with the same IP address. Why it was going for ssh-keygen we don't know.

    Hello,

    My sysadmin and I spent a couple hours trying to figure out a POP3
    problem that has worked for about 20 or so years.

    We run our own dns for sgeinc.com <http://sgeinc.com>.
    I've always used mail.sgeinc.com <http://mail.sgeinc.com> as my
    incoming and outgoing server.  At
    various times mail has been an alias for another machine.  It's
    currently on the same address as sge.sgeinc.com
    <http://sge.sgeinc.com>.  On the update forced
    on us on 2/22/24 or 2/23/24 it stopped working.  It still works as an
    outgoing server but incoming POP3 it stopped working.  It started
    working when I changed my incoming server to sge.sgeinc.com
    <http://sge.sgeinc.com>.
    You might want to look into it or not.  We chased the initial problem
    to, we think, ssh-keygen in /usr/local/bin/ which was Not found but is
    there.


Why would dovecot need ssh-keygen? What for?
