Hello all.  I am running Fedora Core 5 and using it as an SMTP server using postfix.  It is running fine and it is configured for port 465 using TLS/SSL and SMTP Auth.  Again, working fine.

The SSL certificate is about to expire.  I can buy a new one easliy but I don't know the proceedure for renewing and SSL certifcate on Fedora Core 5 using Postfix.  How do I do this?

Cheers
Mark

once the certificate file is in place you only need to change the main.cf file to reflect the files.

take a look at

http://howtoforge.net/perfect_server_fedora7_p5

this page tells you the commands and syntax for the SSL and TLS parts.  you can follow the example or change the files option to point to the new file.

Since my key is about to expire, I generate a new CSR using the command on that page, then get issued a new certificate, then put that in place.  Then postfix will use the new one.  How do I tell what the current certificate info is?

when you are generating the new certificate, the system prompts you to input all the info like country, org name, contact person, sysadmin email etc.
