I read in the manual that changing the TLS configuration for the SMTP server through the
GUI is available only in the 'Enterprise' version,
We've installed a third-party (Digicert) certificate for the Web interface.
Would it be possible to modify the MTA config file to use this Web certificate for SMTP
TLS as well?
It now points to a self-signed certificate I assume:
# server side TLS configuration
smtpd_tls_cert_file = /etc/postfix/tls.pem
smtpd_tls_key_file = $smtpd_tls_cert_file

CipherMail gateway uses Postfix for the MTA part so configuring TLS is
something Postfix specific. You are free to edit most parts of the
Postfix configuration (only the after queue filter and reinjection port
are required for CipherMail).
In the default Postfix main config (main.cf) the TLS config for the SMTP
daemon (smtpd_tls) are commented out (using #). You can remove the
comments and place the certificate and key pem on the file system and
restart Postfix.
An easy way to test the TLS connection on the command line is:
openssl s_client -connect 192.168.88.110:25 -starttls smtp
where 192.168.88.110 is the IP of the SMTP server

I don't see why not. We do the same thing. Just modify your main.cf with your digicert
certificate info.
