/etc/dovecot/conf.d/10-ssl.conf

Primary SSL certificate:

# SSL/TLS support: yes, no, required. <doc/wiki/SSL.txt>
#ssl = yes
ssl = required

("yes" or "required" - I use required)

# Minimum SSL protocol version to use. Potentially recognized values are 
SSLv3,
# TLSv1, TLSv1.1, and TLSv1.2, depending on the OpenSSL version used.
ssl_min_protocol = TLSv1

# PEM encoded X.509 SSL/TLS certificate and private key. They're opened 
before
# dropping root privileges, so keep the key file unreadable by anyone 
but
# root. Included doc/mkcert.sh can be used to easily generate 
self-signed
# certificate, just make sure to update the domains in 
dovecot-openssl.cnf
ssl_cert = </etc/ssl/private/mail-domain-tld.crt
ssl_key = </etc/ssl/private/mail-domain-tld.key

Secondary SSL certificates (I add this at the bottom of the file)

local_name mail.domain2.tld {

         ssl_cert = </etc/ssl/private/mail-domain2-tld.crt
         ssl_key = </etc/ssl/private/mail-domain2-tld.key

}
