Bashscripts.org

At work, I wrote some bash scripts with proccgi to make a form that we enter some information into, then it pulls other data from our ticketing system. The script then assembles an email and sends it to certain people. Who it gets sent to is determined by a selectbox in the form. To increase security, the people who get our emails will now only accept these emails from certain addresses. Is there a way to send emails from the command line that let me specify who the sender is? Or is this something I have to configure in the exim setup? Originally I just used a "heredocument" to pipe the body of the email to the mail command. Now I'm trying to pipe the text of the email to /usr/lib/sendmail -t with the FROM, TO, etc lines being specified, but they still detect it being sent by the webserver user, which they reject.

This form saves us a lot of time typing, any tips will be appreciated.

from the sendmail man page;

-fname Sets the name of the ‘‘from’’ person. This option is valid only if no From: line is specified within the header of the email.

I've heard that on some systems this can only be done by root, but I know that on redhat systems it works ok

if that is an issue you should be able to configure exim to accept that, but i don't know how

I don't know if -fname will help because the /usr/lib/sendmail is just exim, they provide a "sendmail" command for script compatibility, but I'll try it. Maybe I could make the webserver run under a different user and change the domain in /etc/mailname, but it seems like it should be easier to do something on the command line, but then I don't know what that something is! Maybe you can't for security reasons.

You could always write a php script to handle this if CGI can't.

the mail(); function provides you with the possibilty to add headers to your mailed format.
I've done this a couple of times and it works like a charm, even my insanely paranoid smtp allows mails throu as long as all the header information is properly specified.
