Hi!
I have installed an IredMail on FreeBSD 13.
Everything is working, but...

My Posfix main.cf
smtpd_tls_key_file = /etc/ssl/private/iRedMail.key
smtpd_tls_cert_file = /etc/ssl/certs/iRedMail.crt
smtpd_tls_CAfile = /etc/ssl/cert.pem
smtpd_tls_CApath = /etc/ssl/certs

iRedMail.key and iRedMail.crt have a soft link to /usr/local/etc/letsencrypt/live/my.domain.com/privkey.pem and fullchain.pem files accordingly.

smtpd_tls_CAfile = /etc/ssl/cert.pem have a soft link to /usr/local/share/certs/ca-root-nss.crt.

Should I change the soft link on this file to the Letsencrypt certificate file? If so, which certificate file of letsencrypt?

Files in /usr/local/etc/letsencrypt/live/my.domain.com/
