Shell Programming and Scripting

hi all

Does anyone have any ideas on how to improve the performance of mail in AIX ?
When I send a mail, I see a process as below active for a while before actually receiving the mail.

root 311462 1 0 16:02:04 pts/1 0:00 send-mail -i -x abc@xyz.com

Thanks

Hmm, it is still faster than the post office.

About the only thing I can think of is to set up a cache-only DNS server on the mail server (if it isn't set up as a DNS primary or secondary server already). This will allow it to cache DNS information to allow quicker lookups and take maybe another 2-3 seconds off the time to send. You have to remember that it matters on what you are sending (size of email) and where you are sending (they may be getting quite a few mail messages already).

Thanks for the response RTM.
The problem I have is as follows :-
I have a script (A) on host1 that calls a script (B) on host2.
The script (B) on host2 is the one that does the mail. What I see, is if I run script (B) on host2 it goes quick, however when host1 does a rsh on host2 to run script (B) it sits on the mail statement for a while.

Well, that's a completely different problem then you were stating before.

Post the actual command from script B for mail command - change any info such as user/system names to fake ones if needed (keeping the command looking the same so syntax can be checked).

the script on host2 has the following statement in it

LINE=`echo ${HL}${BL}$LINE${RL}`
echo "$MLINE" | mail -s "$HOST - $TEXT" name@domain.com

I forgot to place
MLINE="${DT} | ${HOST} | $ESCRIPT-$MSGID | $TEXT"
