# Post-DATA hook
|
|
|
|
After completion of DATA, but before accepting the mail for queueing, chasquid
|
|
will run the command at `$config_dir/hooks/post-data`.
|
|
|
|
The contents of the mail will be written to the command's stdin, and the
|
|
environment is detailed below.
|
|
|
|
If the exit status is 0, chasquid will move forward processing the command,
|
|
and its stdout should contain headers which will be added to contents of
|
|
the email (at the top).
|
|
|
|
Otherwise, chasquid will respond with an error, and the last line of stdout
|
|
will be passed back to the client as the error message.
|
|
If the exit status is 20 the error code will be permanent, otherwise it will
|
|
be temporary.
|
|
|
|
|
|
This hook can be used to block based on contents, for example to check for
|
|
spam or virus. See `etc/hooks/post-data` for an example.
|
|
|
|
|
|
## Environment
|
|
|
|
This hook will run as the chasquid user, so be careful about permissions and
|
|
privileges.
|
|
|
|
The environment will contain the following variables:
|
|
|
|
- USER
|
|
- SHELL
|
|
- PATH
|
|
- PWD
|
|
- REMOTE_ADDR
|
|
- MAIL_FROM
|
|
- RCPT_TO (space separated)
|
|
- AUTH_AS (empty if not completed AUTH)
|
|
- ON_TLS (0 if not, 1 if yes)
|
|
- FROM_LOCAL_DOMAIN (0 if not, 1 if yes)
|
|
- SPF_PASS (0 if not, 1 if yes)
|
|
|
|
There is a 1 minute timeout for hook execution.
|
|
It will be run at the config directory.
