Sendmail and BusyBox

I checked and realized sendmail daemon is not running...so how can I make it running?  Also, how can I modify ssmtp.conf???
The "telnet" didn't work...how can I make it working???

> sendmail daemon is not running
As root,
find / -type f -name sendmail
to find out where is sendmail first. BusyBox is a special Unix box so the path of sendmail may differ than other Unix.
Or you can check /etc/init.d/sendmail to see where is sendmail daemon (/usr/sbin/sendmail ....)

Please post the result of
uname -a

OK..this is what I got

if I tried "find / -type f -name sendmail", I got nothing
but if I tried "find / -name sendmail", I got those "/usr/lib/sendmail" and "/usr/sbin/sendmail"

and I tried to check /etc/init.d to see whethere there exists sendmail or not...I cannot see it.

find /etc -exec grep -i sendmail {} \ ;

I tried "find /etc -exec grep -i sendmail {} \ ;"
and it seems the pattern is not right...and I got this...
BusyBox v1.00 (2005.02.21-06:42+0000) multi-call binary

Usage: find [PATH...] [EXPRESSION]

Search for files in a directory hierarchy.  The default PATH is
the current directory; default EXPRESSION is '-print'

EXPRESSION may consist of:
        -follow         Dereference symbolic links.
        -name PATTERN   File name (leading directories removed) matches PATTERN.

        -print          Print (default and assumed).

        -type X         Filetype matches X (where X is one of: f,d,l,b,c,...)
        -perm PERMS     Permissions match any of (+NNN); all of (-NNN);
                        or exactly (NNN)
        -mtime TIME     Modified time is greater than (+N); less than (-N);
                        or exactly (N) days
        -newer FILE     Modified time is more recent than FILE's
        -inum N         File has inode number N

Try
/usr/lib/sendmail -bd -q1h
to start sendmail first.

Then
( from remote PC ) telnet <IP address of BusyBox> 25

If all work, then (send test mail)
mail -s "test" <your email address> test  < /dev/null

mMmmm...this is what I got...what should I do now?  @@
# /usr/lib/sendmail -bd -q1h
-bd is not supported by sSMTP

man sendmail
for more details.

Just
/usr/lib/sendmail

OK...seems in my BusyBox, I don't have man...so I tried those commands...

/usr/lib/sendmail -bd -q1h --> it said "-bd is not supported by sSMTP"
/usr/lib/sendmail -bD -q1h --> it said "sendmail: Mail queue is empty"
/usr/lib/sendmail              --> it said "sendmail: No recipients supplied, mail will not be sent"

Ok,
/usr/sbin/sendmail -bd -q1h

I got the same result as I tried "/usr/lib/sendmail -bd -q1h"

How can I fill up "ssmtp.conf"???  Is there any example I can check???
