Ok, I think I should rephrase my question. I did some more research on daemons, and I think I can ask my question better now.

A daemon is a process that runs in the background (like a fork), whithout user interaction (from what I read). So basically what happens is that when an email is received, and the shell script is invoked, a daemon is running the entire process. I need to find a way where I can make the daemon act as if it were a unix user so that the process is run as if the user is the one who is invoking the scripts that are called in the main script, rather than the daemon.

So my basic idea is: email is received, forwarded to a script (daemon is still the owner at the moment), in the main script first thing I want to do is change the user from the deamon to another valid unix account, so then everything that is performed from there on out is performed as if the unix user that I specify is the one who invoked everything.

Does that make more sense? Any ideas?

Thanks

NAME

       script - make record of a terminal session

SYNOPSIS

       script [-a] [filename]

DESCRIPTION

       The  script  utility  makes a record of everything printed on your screen. The record is written to filename. If no file name is given, the
       record is saved in the file typescript. See WARNINGS.

       The script command forks and creates a sub-shell, according to the value of $SHELL, and records the text from this session. The script ends
       when the forked shell exits or when Control-d is typed.

OPTIONS

       The following option is supported:

       -a	Appends the session record to filename, rather than overwriting it.

NOTES

       script places everything that appears on the screen in filename, including prompts.

WARNINGS

       script  can  pose  a  security risk when used in directories that are writable by other users (for example, /tmp), especially when run by a
       privileged user, that is, root. Be sure that typescript is not a link before running script.
