Description-en: addons for the OpenSMTPD SMTP server
The OpenSMTPD server seeks to be
* as secure as possible, and uses privilege separation to mitigate
possible security bugs
* as reliable as possible: any accepted email must not be lost
* lean: it covers typical usage cases instead of every obscure one
* easy to configure, with a configuration syntax reminiscent of the OpenBSD
Packet Filter's (PF)
* fast and efficient: it can handle large queues with reasonable performance
.
This package provides the full set of addons for OpenSMTPD, including
experimental ones. Please see each for a description of additional
dependencies.
* Tables:
+ ldap: support lookup against LDAP
+ mysql: support lookup against MySQL
+ passwd: support lookup in passwd-format tables
+ postgres: support lookup against PostgreSQL
+ redis: support lookup against a Redis server
+ socketmap: support lookups against sockets
+ sqlite: support lookup in SQLite tables
* Filters:
+ clamav: filter mail through clamd [clamav-daemon]
+ dkim-signer: add DKIM signatures to headers
+ dnsbl: perform DNSBL checks
+ monkey: randomly accept mail with a probability of 70%
+ pause: pause on new connections to avoid "slamming" attacks
+ regex: filter mail using regex
