I'll do this one step at a time (I need to do other things).. Again, thank you.
I created the combo with -- Begin Priviate --End Private --Begin Certificate --End Certificate -- Begin Intermediate -- End Intermediate I have one multi-domain certificate, however for email all the emails on server, for mx purposes have the dns mx = mcq.sbanetweb.com. Those who send email through my server have the smtp and imap point to mcq.sba Just the one certificate. You need to append the intermediate CA certificates. PEM format, each starts with "-----BEGIN CERTIFICATE-----" line and ends with an "-----END CERTIFICATE-----" line. In my case: # grep '^---' /...full-path.../combo.pem -----BEGIN PRIVATE KEY----- -----END PRIVATE KEY----- -----BEGIN CERTIFICATE----- -----END CERTIFICATE----- -----BEGIN CERTIFICATE----- -----END CERTIFICATE----- -----BEGIN CERTIFICATE----- -----END CERTIFICATE----- -- Viktor.
