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
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.
- The directory into which the completed messages are
- The directory in which messages are formed
- 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
