Topic: Debian8 does not send emails

I can not connect the iredmail server to send email.

*) Do you have correct SSL cert/key/ca for Postfix?
*) Do all mail clients fail to connect? Or just one?

The e-mail server is separated from the web.

server1 (WEB) : 45.55.44.x
Server2 (ReadMail): 45.77.11.x


when the web server is debian7 works !

Re: Debian8 does not send emails

Dear daemoncesar,

You didn't answer my questions at all. The error log shows a ssl ca related fatal error.

*) Do you have correct SSL cert/key/ca for Postfix?
*) Do you send email from a web program?
*) Do all mail clients fail to connect? Or just one?

Re: Debian8 does not send emails

Does your WHMCS support SMTP over TLS? Please ask WHMCS support or read its document to figure it out.

Re: Debian8 does not send emails

Re: Debian8 does not send emails

*) Do you use a bought SSL cert or Lets Encrypt cert?
*) Does WHMCS verify SSL cert issuer (requires valid SSL cert)?
