NAME
smtp, smtpqer, smtpd, smtpsched - handle simple mail
transfer protocol
SYNOPSIS
/usr/lib/upas/smtp [ option ... ] replyaddr dest recipient
...
/usr/lib/upas/smtpqer [ option ... ] replyaddr dest
recipient ...
/usr/lib/upas/smtpd [ -n ] [ -H host ]
/usr/lib/upas/smtpsched [ option ... ] [ queue ... ]
DESCRIPTION
Smtp reads a mail message from the standard input, and sends
it with the Internet SMTP protocol to the named recipients
at network address dest. Dest has default network tcp and
default service tcp.25 (the conventional Internet SMTP
port). Error reports are mailed to local address replyaddr.
Smtp operates in two modes, `Internet' (default) and `Unix'.
In Internet mode recipient addresses should be in full
domain form. `From:' and `Date:' headers will be inserted
as necessary to conform to Internet standards. In Unix mode
addresses and message contents are not touched. The options
are
-u Run in Unix mode.
-H host
Use host as the name of the sending system (taken from
whoami(5) by default).
-d domain
Append the specified domain suffix to incomplete
addresses.
Smtpqer reads a mail message from the standard input and
stashes it away to be sent later by smtpsched. By default,
smtpsched is started immediately; option -n prevents this.
Other options and arguments are the same as for smtp.
Smtpd receives a message by speaking the server part of SMTP
on the standard input and output. The message is stashed in
a queue for later delivery as by smtpqer. Option -n prevents
smtpsched from running immediately; option -H is as for
smtp.

Smtpsched processes the queues assembled by smtpqer and
smtpd, calling mail(1) for local messages and smtp for oth-
ers. It should be run occasionally from cron(8).
The queue arguments name particular queue directories to be
processed; if no queue is named, all queues are processed.
The options are
-w days Send a warning about each message more than days
old to the reply address.
-r days Mail an error reply about each message more than
days old, and discard the message.
-s nproc Do not run more than nproc simultaneous copies of
smtpsched started with this option.
-c Remove empty directories and inconsistent files.
-t Log actions without performing them.
-C Process `C' command files (smtp calls) only.
-X Process `X' command files (rmail calls) only.
-v Enable verbose logging.
The queues are kept in subdirectories of named by splitting
the lower case remote system name into components separated
by periods, concatenating the last two or fewer components,
taking the last 14 characters, and stripping leading peri-
ods.
