Im just setting up my emailserver and want it to be SSL secured with a valid certificate, so I got a Comodo positivessl cert. As I use multiple domains, I needed a SAN cert, which I got. What is in the package I received after the process is:
<my_san_cert>.crt AddTrustExternalCARoot.crt COMODORSAAddTrustCA.crt COMODORSADomainValidationSecureServerCA.crt
So from what I understood, I have to bundle the last three files, which I did, to a bundled file. Now I need to put it in the
smtpd_tls_cert_file = /some/path/yourdomain.crt smtpd_tls_key_file = /some/path/yourdomain.key smtpd_tls_CAfile = /some/path/ca.txt (bundle file)
What I do not get, where is my keyfile? Is it the private key used for the request of the certificate?
Thanks in advance!
