Description

This cookbook installs and configures exim4 for client or outbound relayhost.

Build Status

Requirements

Platform:

  • Debian 6.0+

May work on other platforms with or without modification.

Attributes

See attributes/default.rb for default values.

  • node['exim4']['user'] - The exim4 user.
  • node['exim4']['configtype'] - The main configuration type. One of internet, smarthost, satellite, local or none.
  • node['exim4']['other_hostnames']- Is used to build the local_domains list, together with `localhost. This is the list of domains for which this machine should consider itself the final destination.
  • node['exim4']['local_interfaces']- List of IP addresses the Exim daemon should listen on. If this is left empty, Exim listens on all interfaces.
  • node['exim4']['readhost']- For smarthost and satellite it is possible to hide the local mailname in the headers of outgoing mail and replace it with this value instead, using rewriting.
  • node['exim4']['mailname']- The visible mail name of the system (see also /etc/mailname).
  • node['exim4']['relay_domains']- Is a list of domains for which we accept mail from anywhere on the Internet but which are not delivered locally, e.g. because this machine serves as secondary MX for these domains.
  • node['exim4']['minimaldns']- Boolean option to activate some option to minimize DNS lookups.
  • node['exim4']['relay_nets']- A list of machines for which we serve as smarthost. Please note that 127.0.0.1 and ::1 are always permitted to relay since /usr/lib/sendmail is available anyway and relay control doesn't make sense here.
  • node['exim4']['use_split_config']- Boolean option that controls whether update-exim4.conf uses /etc/exim4/exim4.conf.template (false) or the multiple files below /etc/exim4/conf.d (true) as input.
  • node['exim4']['hide_mailname']- Boolean option that controls whether the local mailname in the headers of outgoing mail should be hidden. (Only effective for smarthost and satellite.
  • node['exim4']['localdelivery']- Name of the default transport for local mail delivery. Defaults to mail_spool if unset, use maildir_home for delivery to ~/Maildir/.
  • node['exim4']['smarthost_server']- Server to which all outgoing mail is passed to and that takes care of delivering it. All deliveries go out to TCP port 25 unless a different port is specified (use smarthost_port). Colons in IPv6 addresses need to be doubled. If a port number follows, IP addresses may be enclosed in brackets, which might be the only possibility to specify delivery to an IPv6 address and a different port.
  • node['exim4'][smarthost_port] - TCP port for the mail server. If no port is given exim uses 25 by default.
  • node['exim4']['smarthost_login']- Login used for the smarthost.
  • node['exim4']['smarthost_pwd']- Password used for the smarthost.
  • node['exim4']['encrypted']['enabled']- Enable usage of encrypted data bag for smarthost credentials.
  • node['exim4']['encrypted']['bag']- Name of the encrypted data bag.
  • node['exim4']['encrypted']['item']- Name of the encrypted data bag item.
  • node['exim4']['other_options'] - Hash of other options for update-exim4.conf.conf.

Usage

Include the recipe[exim4-light] in your node or role runlist. By default exim4 will be unconfigured. Set at least the node['exim4']['configtype'].

It is recommended to use an encrypted data bag to store your credentials. To enable this feature, set node['exim4']['encrypted']['enabled'] to true and set the data bag and item names accordingly.
