If you want to send mail from the nslu2 containing a message, you can do it by using the smtpclient program. By piping in the message, give it the options of sender address, subject, and recipient and it will send the message:
The -v shows you what it does. The -P option, point it to the (relaying) mailserver, doesn't work on this build. So it contacts the mailserver of the recipientdomain.com directly, if it can.
To mail a directory listing, just do:
The --help option gives more stuff:
Usage: smtp [options] recipients ...
Message Header Options:
-s, --subject=STR subject line of message -f, --from=ADDR address of the sender -r, --reply-to=ADDR address of the sender for replies -e, --errors-to=ADDR address to send delivery errors to -c, --carbon-copy=ADDR address to send copy of message to
-S, --smtp-host=HOST host where MTA can be contacted via SMTP -P, --smtp-port=NUM port where MTA can be contacted via SMTP -M, --mime-encode use MIME-style translation to quoted-printable -L, --use-syslog log errors to syslog facility instead of stderr
-v, --verbose enable verbose logging messages -V, --version display version string -h, --help display this page
But as I said not all options work in this build.
