SSL Certificate using Dovecot IMAP Server


depth=1 C = US, O = “CloudFlare, Inc.”, OU = CloudFlare Origin SSL Certificate Authority, L = San Francisco, ST = California

verify error:num=19:self signed certificate in certificate chain

verify return:0

You cant (really) use an origin certificate in an IMAP context, as these are only trusted by Cloudflare’s proxy servers and those dont do IMAP.
