I 'm trying to do a simple mail sending script.
First, if I telnet (by-hand) to any server and
put the following commands, it works fine:
HELO my_domain
MAIL FROM: my_address
RCPT TO: dest_address
DATA
( ... data ... )
.
quit
BUT: if I save a file with that exacts commands and
do the telnet batch like:
telnet smpt_server 25 < my_file
works with some servers and no with others.
With my Unix servers, it works. With a
Microsoft Exchange server, it doesn 't.
The only difference I see is that the Exchange
server is very much slower than the Unix. I mean,
I have to wait about 1seg to it to give me the prompt.
Any ideas ?
I know there are some perl modules to do this. But
I have to do it in KSH.
Thanks

Here is a little shell script ... Please note the "sleep"
is important. Otherwise the script will flood the port and
it won't work.
#!/bin/sh
# Send a test message
# Usage: myscript mailhost
#
# If ping reachable (Under Solaris 2.5.x)
if ping $1 3
then
{
echo HELO mydomain.com # send domain name
sleep 1 # wait 1 seconds for answer
echo MAIL FROM: test@abc.com # send passwd
sleep 1
echo RCPT TO: test@whateverdomain.com # send userid@host
sleep 1
echo DATA
sleep 1
echo this is a test
echo line 2
echo .
echo quit
} | telnet $1 25
fi
You could intergrate this into what ever scripting shell you want.
