set SSL_DOMAIN=*.example.com to extract a wildcard certificate from traefiks acme.json store
 2020-07-13 22:58:17 +02:00
Michael Sprauer 3a3cec6a8f trigger reload if cert change 
/etc/letsencrypt/live/$HOSTNAME/key.pem  and /etc/letsencrypt/live/$HOSTNAME/fullchain.pem are watched and will trigger a reload if changed

Michael Sprauer 32c732e276 certificates from acme.json 
Will extract certificates from acme.json as written by traefik for usage in dovecot and postfix.
Also watches acme.json for changes. For this to work the file has to be mounted/present at `/etc/letsencrypt/acme.json`

Nicholas Pepper 1b659a5574 Modified letsencrypt support to add domain name checking in addition to 
hostname checking.  Added necessary tests and renamed original manual
ssl test to a name that supports adding the other SSL tests.

chore: Remove obsolete postfix parameter `smtpd_use_tls`
 2020-04-30 08:02:11 +02:00
Brennan Kinney 76594c21c4
Add note about tls_ssl_options = NO_COMPRESSION 
[Postfix docs](http://www.postfix.org/postconf.5.html#tls_ssl_options):

> Disable SSL compression even if supported by the OpenSSL library. Compression is CPU-intensive, and compression before encryption does not always improve security.

[Postfix mailing list discussion](http://postfix.1071664.n5.nabble.com/patch-mitigate-CRIME-attack-td57978.html):

> The CRIME attack does not apply to SMTP, because unlike SMTP, there is no javascript in SMTP clients that makes them send thousands of email messages with chosen plaintext compressed together in the same packet with SASL credentials or other sensitive data.
> The auditor completely failed to take the context into account.

[Mailing list discussion of potential compression CRIME-like attack](https://lists.cert.at/pipermail/ach/2014-December/001660.html)

> keeping compression disabled is a good idea.

If you need a good test score, PCI compliance will likely flag compression despite not having any known risk with non-HTTP TLS.
