This plugin introduces the foodcoop config option `use_messages`, which can be
|
||||
set to `false` to disable messages. May be useful in multicoop deployments.
|
||||
|
||||
To allow members to respond to messages via email, see the config option
|
||||
`reply_email_domain` and the rake task `foodsoft:parse_reply_email`. We need to
|
||||
add some documentation on setting it up, though.
|
||||
To allow members to respond to messages via email, you need the set the config
|
||||
option `reply_email_domain` and handle incoming mails via one of the following
|
||||
rake tasks. `foodsoft:reply_email_smtp_server` starts an SMTP server on the
|
||||
port given via the environment variable `PORT` and listens until a shutdown
|
||||
signal is received. If there is already a SMTP server for handling incoming
|
||||
mails you can also feed every mail via a call to `foodsoft:parse_reply_email`
|
||||
into foodsoft. It expects the address given in the `MAIL FROM` command via
|
||||
SMTP in the environment variable `RECIPIENT` and the mail body as `STDIN`.

||||

||||

|
||||
foodsoft's LICENSE for the full license text).
