Hello,

for one website I use PHPMailer 6.0.1.

When I have configered $SMTPAutoTLS = true then mail is not being send and I have following error in the mainlog:

2017-12-18 12:58:38 TLS error on connection from srv.server.com (www.domain.be) [00.00.00.00] (SSL_accept): error:14094418:SSL routines:ssl3_read_bytes:tlsv1 alert unknown ca
2017-12-18 12:58:38 TLS client disconnected cleanly (rejected our certificate?)


When I put $SMTPAutoTLS = false mail is being send. But is it possible to use TLS or not?

I think it's an error about the certificate.

The domain has a certifcate for domain.be and www.domain.be
There is not certificate for srv.server.com only for server.com and www.server.com

May this be the error?
Should I have a certificate also for srv.server.com (I don't use this domain for my website, it's only the name of the server)
 
Hello,

If you don't use Mail SNI and your domain's cert is not added into Exim then you need either to connect to a hostname or install your domain's cert into Exim.
