First, some baseline data:
r...@server:~# cat /etc/mailer.conf | grep -v '^#'
sendmail /usr/sbin/smtpd
send-mail /usr/sbin/smtpctl
mailq /usr/sbin/smtpctl
makemap /usr/libexec/smtpd/makemap
newaliases /usr/libexec/smtpd/makemap
Not sure if this is right or not, it doesn't seem to be documented
anywhere yet.
r...@server:~# cat /etc/mail/smtpd.conf | egrep -v '^#|^$'
ExtIF = "fxp0"
IntIF = "em0"
listen on lo0
listen on $ExtIF
listen on $IntIF
map "aliases" { source db "/etc/mail/aliases.db" }
accept from all for domain "athompso.net" deliver to mbox
accept from 127.0.0.1 for local deliver to mbox
accept from 192.168.206.0/24 for local deliver to mbox
accept from 192.168.206.0/24 for all relay via
shawmail.wp.shawcable.net
Note, last line may be wrapped in this post, not in the file.
I've run newalises (exec'ing /usr/libexec/smtpd/makemap, via mailwrapper
as appropriate).
Now, when I try to mail myself something local:
r...@server:~# smtpd -v

so far so good...

Finished initialization here.
Ran "mail root" on another console, with identical results as before,
but here's the debug output:

smtp_dispatch_mfa: mfa handled return path
session_destroy: killing client: 0x7cafa000
So... I have no idea what all that output means, but I do note that
there's not a single thing in it I would call an error message.
OTOH, if I do this:
r...@server:~# telnet localhost 25
Trying 127.0.0.1...
Connected to localhost.
Escape character is '^]'.
220 server.athompso.net ESMTP OpenSMTPD

then I get additional debug output which *does* look different:

So... altering /etc/mailer.conf to read:
send-mail /root/test.sh
where /root/test.sh consists merely of:
#!/bin/sh
set +x
echo "Invoked as: $0 $@"
while read X; do echo $X; done
I get this output:
r...@server:~# mail root
Subject: test
test
.
EOT
r...@server:~# Invoked as: /root/test.sh -i -- root
To: root
Subject: test
test
r...@server:~#
Which looks pretty much exactly like I expected. (Obviously, there's no
additional debug output from smtpd -d -v, since we didn't *do* anything
except echo back some data.
So. WTF am I doing wrong? Help!
