I am running Solaris 8 on a SUN 450 and need to have e-mails sent out each month for several systems to remind users to take certain actions. I can successufully add a job to the cron, but each time the mailx sends an e-mail it has my user ID along with telephone number as the sender. I would like to have each system be the sender, like system1@mailserv.com
system2@mailserv.com. is there a way to do this using my ID without seting up a UNIX id for each system?

This is not ideal, but you could do something like:


( echo "From: someone@somewhere"; \
echo "To: someone@somwhereelse"; \
echo "Subject: some subject"; \
echo ""; \
echo "Body of email"; \
) | sendmail -t


A better solution would be to use perl and the Mail::Mailer module.

also i think you could create a new user with whatever name you want, ie "system1" and then create the cronjob with that user

As PxT replies, the sendmail -t option is very useful for these situations. From the sendmail manpage:

My suggestion would be to create a file with the appropriate header fields and concatonate with the body (and send) via cron.
