* MSA: Update role to Debian Buster.Guilhem Moulin2020-05-191
| | | | | | | | For `ssl_cipher_list` we pick the suggested value from https://ssl-config.mozilla.org/#server=postfix&version=3.4.10&config=intermediate&openssl=1.1.1d At the moment it's equivalent (modulo order) to adding ‘EDH+AESGCM+aRSA’ to ‘EECDH+AESGCM:EECDH+CHACHA20!MEDIUM!LOW!EXP!aNULL!eNULL’.
* AEAD ciphers: Add EECDH+CHACHA20 macro.Guilhem Moulin2020-05-181
| | | | | | | This adds the following two ciphers: ECDHE-ECDSA-CHACHA20-POLY1305 TLSv1.2 Kx=ECDH Au=ECDSA Enc=CHACHA20/POLY1305(256) Mac=AEAD ECDHE-RSA-CHACHA20-POLY1305 TLSv1.2 Kx=ECDH Au=RSA Enc=CHACHA20/POLY1305(256) Mac=AEAD

* Postfix: disable DNS lookups on the internal SMTPds.Guilhem Moulin2020-01-231
| | | | | | Our internal IPs don't have a reverse PTR record, and skipping the resolution speeds up mail delivery. http://www.postfix.org/postconf.5.html#smtpd_peername_lookup
* MSA: Open 465/TCP for Email Submission over TLS.Guilhem Moulin2019-03-191
| | | | See RFC 8314 sec. 3.3 "Cleartext Considered Obsolete".
* submission: Prospective SPF checking.Guilhem Moulin2018-12-121
| | | | Cf. http://www.openspf.org/Best_Practices/Outbound .
* MSA verification probes: enable opportunistic encryption.Guilhem Moulin2018-12-091
| | | | | | And use ‘noreply.fripost.org’ as HELO name rather than $myhostname (i.e., ‘smtp.fripost.org’), so the same SPF policy can be used for ehlo and envelope sender identities.
* MX: chroot postscreen(8), smtpd(8) and cleanup(8) daemons.Guilhem Moulin2018-12-091
| | | | | | Unlike what we wrote in 2014 (cf. 4fb4be4d279dd94cab33fc778cfa318b93d6926f) the postscreen(8) server can run chrooted, meaning we can also chroot the smtpd(8), tlsproxy(8), dnsblog(8) and cleanup(8) daemons.

* Postfix: replace 'fifo' types with 'unix', as it's the new default.Guilhem Moulin2018-04-041

* postfix: enable XFORWARD command from our internal relays.Guilhem Moulin2017-06-021
|
* postfix: don't rate-limit our IPsec subnet.Guilhem Moulin2017-06-021

* Don't let authenticated client use arbitrary sender addresses.Guilhem Moulin2017-06-011
| | | | | | | | | | | | | | The following policy is now implemented: * users can use their SASL login name as sender address; * alias and/or list owners can use the address as envelope sender; * domain postmasters can use arbitrary sender addresses under their domains; * domain owners can use arbitrary sender addresses under their domains, unless it is also an existing account name; * for known domains without owner or postmasters, other sender addresses are not allowed; and * arbitrary sender addresses under unknown domains are allowed.
* Route all internal SMTP traffic through IPsec.Guilhem Moulin2016-07-101

* Postfix: don't share the master.cf between the instances.Guilhem Moulin2016-07-101
