OK I'll try, I just found out there are multiple versions in my various
deployed systems and as they don't have a version stamp I cannot know
what you have.
My home system looks like the latest in Bering 4 and works indeed. One
system at a remote location had a line starting with 'source' and this
is a wrong keyword for that specific version of busybox. So if you have
that version
Anyway I tested with my home gateway and here is the first result
gatekeeper# mail -s foo -h 194.124.158.51 erich.t...@think.ch
hostname: gatekeeper: Unknown host
Debugging shell scripts is pretty easy....
gatekeeper# which mail
/usr/sbin/mail
gatekeeper# sh -x /usr/sbin/mail -s foo -h 194.124.158.51
erich.t...@think.ch

+ hostname -f
hostname: gatekeeper: Unknown host
So this looks like the hostname call is wrong......
gatekeeper# which hostname
/bin/hostname
gatekeeper# ls -l /bin/hostname
lrwxrwxrwx 1 root root 12 May 18 18:33 /bin/hostname ->
/bin/busybox
Fine, so how should hostname look like
gatekeeper# hostname --help
BusyBox v1.8.2 (2008-01-05 01:22:22 UTC) multi-call binary
Usage: hostname [OPTION] {hostname | -F FILE}
Not much information, but maybe busybox's website can tell more
hostname
hostname [OPTIONS] [HOSTNAME | -F FILE]
Get or set hostname or DNS domain name
Options:
-s Short
-i Addresses for the hostname
-d DNS domain name
-f Fully qualified domain name
-F FILE Use FILE's content as hostname
OK, so -f should yield the FQDN
gatekeeper# hostname -f
hostname: gatekeeper: Unknown host
Looks like a busybox bug to me. Now as hostname should just take what is
set on the system, where could it get the domain from? One bet is
/etc/resolv.conf, and there is no domain defined in my case, so I set a
domain entry in /etc/resolv.conf, just for fun.
gatekeeper# hostname
gatekeeper
gatekeeper# hostname -f
gatekeeper.think.ch
Hey, all of a sudden there is no error in the mail program anymore. Not
really sophisticated as a solution, but as long as it works....
My example here does not need any settings in /etc/POSIXness, but
setting reasonable values there help even with the hostname -f problem
#This is the master config file for the POSIXness.mail scripts
# Host SMTP server for the 'mail' command. If blank the host 'mail' is used.
MAIL_SERVER="194.124.158.51"
# From: domain to send to mail server. If blank, `hostname -f` is used.
MAIL_DOMAIN="mydomain.net"
# Return-Path will be USER@MAIL_DOMAIN
USER="foodle"
Now one more try...
gatekeeper# mail -s foobar erich.t...@think.ch
scoobly oobly doobab
And here is the mail
>From foo...@mydomain.net Mon Jun 13 23:35:01 2011

Hope this helps, if you run into another problem due to a different
script/busybox match let me know.
cheers
