How to disable verify certificate for sending email

[congnghiakhiem]

I have tried to send email from my own postfix server. But I have a problem with my certificate.
Therefore I need to disable verification. Please help me how to do this.

Disabling makes no sense and breaks the rules.

If your EspoCRM-Server is Linux based e.g. Debian, copy your crt file (Public Key) from your Certficate Authoritiy to:
/usr/local/share/ca-certificates/

Example: your-ca.crt

From console type:
update-ca-certificates

If reply is "1 added" it is done.

Note: The crt must be from your CA, not from your Mailserver.
