I am using self signed certificate pair (.key and .crt) for my company's mail server. All personel has the .crt file imported and trusted in theirs mail clients.
An year ago when I created the certs, it was only experimental, but it was ok and now all employer's computers are configured to send and receive mail through smtps and pop3s.
Is there any chance to extend sertificate expirty date? Do I have to create new certificate?
I'm a bit noob with ssl certificates.. and it didn't come to my mind that the certificate will expire after one year. Now I am facing the problem that very soon all users will become unable to use their emails. And my users are in different places and most of them dont have skills to reconfigure their mail clients.
I am looking for a solution that doesnt require client actions...
I hope it is possible
10x in advance
p.s. the mail server machine is with FreeBSD 7.1-RELEASE-p2 (i386)
smtp - exim-4.69_2
pop3 - dovecot-1.1.8
