Lets Encrypt TLS set up
Lets Encrypt TLS set up
Happy Weekend to ALL.
let me start by saying thanks to all the hard work you guys/girls put into Sentora.
I've spent the last 2 days wading through endless posts & threads
all asking the same question with different answers.
Could not fing a strainght forward guide...
I also done hundreds of searches on the forum for the simple answer..

this is what i've done so far is:

1. used this thread
(Secure Sentora Domains with Let's Encrypt)
to get cert for

2. used this thread
(Ubuntu: How to setup TLS on postfix and dovecot)
started at no3

nano /etc/postfix/

4: find # tls config and added

smtp_use_tls = no
smtpd_use_tls = yes
smtpd_tls_security_level = may
smtp_tls_note_starttls_offer = yes
smtpd_tls_loglevel = 1
smtpd_tls_received_header = yes
smtpd_tls_session_cache_timeout = 3600s
tls_random_source = dev:/dev/urandom
smtp_tls_session_cache_database = btree:$data_directory/smtp_tls_session_cache
smtpd_tls_key_file = /etc/letsencrypt/live/mail.domain.tld/privkey.pem
smtpd_tls_cert_file = /etc/letsencrypt/live/mail.domain.tld/cert.pem
smtpd_tls_CAfile = /etc/letsencrypt/live/mail.domain.tld/fullchain.pem

and removed  what was there before Smile

5: edit (did what the guide said)


6: configure Dovecot

nano /etc/dovecot/dovecot.conf

and changed
ssl = no to ssl = yes
  and added this below it:

ssl_key = </etc/letsencrypt/live/mail.domain.tld/privkey.pem
ssl_cert = </etc/letsencrypt/live/mail.domain.tld/cert.pem
ssl_ca = </etc/letsencrypt/live/mail.domain.tld/fullchain.pem

service postfix restart
service dovecot restart
