But mail to home.isbd.net fails.
Try sending an entire message? Type the following:
$ telnet 127.0.0.1 25
helo localhost.localdomain
mail from: home@locahost
rcpt to: root
data
test message
.
quit
OK, here you go:-
home$ telnet 127.0.0.1 25
Trying 127.0.0.1...

... and that has been delivered to root. Similarly mail sent to
'chris' works too. Huh!?
Just a minute.....
Ah, I'm beginning to understand, mail to 'chris' and 'root' works, but
sendmail would appear to add a hostname to what's sent by an MUA and
anything with a hostname after the username is sent out, which doesn't
work.
Well I'm flummoxed.
You can send mail directly with sendmail too, and there are some very
fancy debugging options you can read up on, Chris.
But first, how to send mail with netcat. This is slightly obfuscated:
06:33 [summer@numbat ~]$ cat /home/summer/testmail | sed -e 's=ei=ie='
#!/bin/bash
nc <<Z $1 25
ehlo corridors.wa.edu.au
MAIL FROM: summer@xxxxxxxxxxxxxxxx
