Hi

AFAIK, this should be configuren on smtpd_recipient_restrictions using
check_recipient_access. Please, let me know if I'm wrong.
It's not working, so maybe it's because I don't know if rules are applied

No need to clutter the configuration with overzealous low-level
Hi Viktor.
Please check my original post. Your comments are on the postfix defaults
and not my current settings.
as for why I set these explicitly, I figured that more random bits means
more secure.
tls_random_bytes = 64
tls_daemon_random_bytes = 64

I’ve posted several times about the problems that I’m having getting roundcube
to send mail through postfix. I think you can throw out all the previous posts
and start anew.
In one exchange, Victor pointed out that I did not have -o
smtpd_tls_wrappermode=yes set in master. (It was commented

Nit: always_add_missing_headers is a cleanup(8) daemon feature.

the host configuration for roundcube should be FQDN.
for example, mine is:
$config['imap_host'] = 'ssl://mail.tls-mail.com:993';
$config['smtp_host'] = 'ssl://mail.tls-mail.com:465';
you can't use something like:

May seem a strange question, but it's always first thing I check in case I
don't see any connection attempt in logs: Is your Roundcube
Does your roundcube config.inc.php have the smtp_host as
'tls://mail.stovebolt.com:587'; ? It will need the FQDN and not
