Short answer: you shouldn't.
Long version: it is simply not the task of a script to "know how to deliver mails". This should be the knowledge of the mailing daemon and be configured there. "mail" (which you use in your script) is a client program which acts as a frontend to this delivery system: it takes a mail message with all relevant information (addressee, content, subject line, etc.) and passes this to a daemon (sendmail, whatever), which should deliver this to an MTA (mail transfer agent) or to the addressees systems mail service directly. In any case your script should not be concerned with how mail gets there.
To use an analogy: if you want to use any other IP service (say, FTP) in your script, it shouldn't be concerned in dealing with IP routing or something such either - this would be the job of routers, so let them do it.
Bottom line: configure your "sendmail" or whatever you use to send mails properly and leave your perfectly written script alone.
I hope this helps.

escape(1) Mail Avenger 0.8.3 escape(1)
NAME
escape - escape shell special characters in a string
SYNOPSIS
escape string
DESCRIPTION
escape prepends a "" character to all shell special characters in string, making it safe to compose a shell command with the result.
EXAMPLES
The following is a contrived example showing how one can unintentionally end up executing the contents of a string:
$ var='; echo gotcha!'
$ eval echo hi $var
hi
gotcha!
$
Using escape, one can avoid executing the contents of $var:
$ eval echo hi `escape "$var"`
hi ; echo gotcha!
$
A less contrived example is passing arguments to Mail Avenger bodytest commands containing possibly unsafe environment variables. For
example, you might write a hypothetical reject_bcc script to reject mail not explicitly addressed to the recipient:
#!/bin/sh
formail -x to -x cc -x resent-to -x resent-cc
| fgrep "$1" > /dev/null
&& exit 0
echo "<$1>.. address does not accept blind carbon copies"
exit 100
To invoke this script, passing it the recipient address as an argument, you would need to put the following in your Mail Avenger rcpt
script:
bodytest reject_bcc `escape "$RECIPIENT"`
SEE ALSO

BUGS
escape is designed for the Bourne shell, which is what Mail Avenger scripts use. escape might or might not work with other shells.
