Thanks, but i already tried that , although i am not able to send email from that as well. it keeps loading without any error.
I commented tls_advertise_hosts = * and i am able to send email from port 25/587 and getting 10/10 on http://mail-tester.com
however email still goes into pan specially in gmail.
I am desperate to resolve the issue. If i uncomment tls_advertise_hosts line in /etc/exim/exim.conf i get the same error "Unable to use STARTTLS".
NOw i have used letsencrypt as well but same issue.
