Re: Validating certificate chain of SMTP TLS connections using privately-issued CA certsy

[Thomas Bohl]

client# cat /tmp/server.crt >> /etc/ssl/certs.pem

BTW it's /etc/ssl/cert.pem not /etc/ssl/certs.pem



Not the cert of the server but, like he said, the CACert.pem

The certificate is self-signed. Sorry, I should have mentioned that.

Especially since you started by saying "A private CA has issued server 
certs to mail.example.org." :-) You could just create your own CA...


Just go with free "ACME certificate".)

Not possible.

...or do not have control over mail.example.org?
