Recreating SSL Certificates
My SSL certs, used for secure POP3 email retrieval and https access
to SquirrelMail, both expired on the same day, one year after they'd
been generated. On my FC1 box, Dovecot was NOT being used although it
was installed. Rather, the IMAPD package included pop3s which was
launched via xinetd. When the certs expired, I could still access
both services, but each time I'd get a message saying the cert from
the server had expired, which got annoying after a while.
To create a new cert for POP3s, see the
Red Hat 9 Manual.
Scroll about halfway down and you'll see the relevant 'make ipop3d.pem' command.
For Apache, see
http://www.rpatrick.com/tech/makecert/ for a quick list of steps on
how to generate a new key & cert and where to put them.
See the Dovecot section at the bottom of
this CentOS page for instuctions on generating the SSL certs for use with
dovecot and its IMAP and POP3 services. This should be used instead of the pointer above to
the Red Hat document.
