nullmailer-queue - insert mail messages into the queue
This program reads a formatted mail message from standard input and safely injects it into the outgoing mail queue.
The data sent into standard input is expected to have the following format: one line containing the envelope sender, one or more lines containing the recipients, a single blank line, and then the contents of the message exactly as it is to be transmitted to the destination. All lines are terminated with a single line-feed character. All addresses must contain a fully-qualified domain name.
Exits 0 if it successfully queues the message. If it failed to queue the message, it exits 1 and prints an error message to stdandard output.
- If this file is not empty, all recipients to users at either "localhost" (the literal string) or the canonical host name (from /etc/mailname ) are remapped to this address. This is provided to allow local daemons to be able to send email to "somebody@localhost" and have it go somewhere sensible instead of being bounced by your relay host. To send to multiple addresses, put them all on one line separated by a comma.
- If this file is not empty, its contents will override the envelope sender on all messages.
- The directory into which the completed messages are moved.
- The directory in which messages are formed temporarily.
- A pipe used to trigger nullmailer-send to immediately start sending the message from the queue.
This program should enforce system-wide configurable message length limits.
