2015-04-28Reject inbound mail to local system users that don't appear invarac
/ect/aliases #6829 We began to recieve spam for vmail@DOMAIN. So we want to block inbound mail to local system users. However, users in the /etc/aliases file are still accepted on inbound mail - see https://leap.se/code/issues/6909 for a follow up. Change-Id: I03d3014984c4bd27f90147125fb037b68716624d

2014-04-02Fix for satellite hosts that are unable to contact their relayhostMicah Anderson
because the DNS lookup is either impossible (.local domain), or incorrect (certain openstack/amazon/piston cloud configurations create this setup when the relayhost is in the same cluster as the satellite). Fixes #5225 Change-Id: Ifbc201678f2c0e97ee0e12bbf1c7f71d035d45c1

2013-10-06only use TLSv1 or later for smtp (Feature #4011)Micah Anderson
Disable on the client-side with postfix (smtp) SSLv2/SSLv3 and only allow for TLSv1 or later SMTP servers almost universally support TLSv1. There are very few servers that don't (the few that are would result sending in the clear for these, but the alternative isn't much better). This is unlikely to cause any significant problems.

2013-08-29Make TLS-required smtps (465) be port for sending SMTP. This is preferred ↵Micah Anderson
over 25 because that is typically blocked, and we cannot force TLS on that port due to other MTAs not being configured for this century. We don't use submission (568) because that uses STARTTLS, and the STARTTLS banner can easily be stripped by an adversary. (#3604) . enable smtps (port 465) for client submission over TLS, and require that TLS is enabled . add 465 to the allowed open ports in the firewall . change the smtp-service.json to use 465 instead of 25 note: I did not use the 'use_smtps' parameter that is available in the postfix class because it added some options that we do not want/need.
