Deliver delivers E-Mail on the local system.
|
||
|
|
|
||
|
|
Deliver allows any user to write a shell script that processes all
|
||
|
|
incoming mail messages for that user. The system administrator may
|
||
|
|
also install scripts that process all messages.
|
||
|
|
|
||
|
|
The output of a script is a list of mail addresses, files and programs
|
||
|
|
that should receive the message. It has access to each message as it
|
||
|
|
is processed, so the action can be content dependent. The script may
|
||
|
|
also generate automatic replies, like the "vacation" program, or pass
|
||
|
|
along a modified version of the original message.
|
||
|
|
|
||
|
|
Deliver can be used to construct mail-based services (e.g. automatic
|
||
|
|
mailing list maintenance). It can also be used to filter mail
|
||
|
|
automatically in prearranged ways (e.g. encryption and decryption,
|
||
|
|
tossing junk mail, or vacation notices).
|
||
|
|
|
||
|
|
Although deliver works best when installed set-user-id root, it can
|
||
|
|
perform many of its functions even when installed in the private bin
|
||
|
|
directory of a regular user.
