Default How to renew SSL certificates for postfix SMTP


I've been running a ISPConfig 3 server on debian lenny with success, but now my certificate for SMTP needs to be renewed. I followed the guide "The perfect server" and I guest it's a cert for postfix? How do I renew? Can I make a cert that lasts for ever?

Kind regards, Bjarne

I had the same problem and haven't found a suitable solution.
So I collected the information of many internet pages and finally got it working.
To remember how it runs I documented the steps in my wiki:


Sorry, but I don't want to adapt the steps to this forums syntax, because I'd like to sleep now

if you use a courier, so this is working for me:

cd /etc/courier
rm -f /etc/courier/imapd.pem
rm -f /etc/courier/pop3d.pem


/etc/init.d/courier-imap-ssl restart
/etc/init.d/courier-pop-ssl restart
