Can't sending mail with STARTTLS or SSL/TLS

Postby Spheerys » Wed Aug 16, 2017 12:23 pm

Hi,

Since few days, I can't send email with STARTTLS or SSL/TLS activated.
On the log, I have this :

Code: Select all

2017-08-16 14:18:55 TLS error on connection from [78.213.xx.yy] (recv): A TLS fatal alert has been received.: CA is unknown
2017-08-16 14:18:55 TLS error on connection from [78.213.xx.yy] (send): The specified session has been invalidated for some reason.


What's wrong ?

Strange thing : I have this problem only on one domain.
The others ones are still working with STARTTLS or SSL/TLS

Maybe could it be a certification regeneration ?

I don't know about the certificat.
I think the certs are auto-generated by the server, but I'm not sure the problem comes form this point...
