I would like to use an existing bought certificate in order to secure the ISPConfig3.1 mail services, I think, replacing the self-signed certificate made during the ISPConfig installation. Thanks.
The steps are described here: https://www.howtoforge.com/securing...h-a-free-class1-ssl-certificate-from-startssl Just use your own SSL cert instead of getting one from startssl.
I was a bit confused having received only two files: a bundle ca and the certificate (as .crt). Many parts could be obvious for many but not for everyone so here's what I did. First I put my private key into ispserver.key. Second I copied my .crt content into /usr/local/ispconfig/interface/ssl/ispserver.crt Code: nano /usr/local/ispconfig/interface/ssl/ispserver.crt Next, instead of downloading "Root CA and the Class1 Intermediate Server CA" I copied first part of bundle into sub.class1.server.ca.pem and the second part into ca.pem Where parts are delimited by "-----BEGIN CERTIFICATE-----" and "-----END CERTIFICATE-----" (included). For the rest I followed the instructions except for having replaced the occurrences of "startssl" with the name of my certificate.
