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.

showq

SHOWQ(8)						      System Manager's Manual							  SHOWQ(8)

NAME

       showq - list the Postfix mail queue

SYNOPSIS

       showq [generic Postfix daemon options]

DESCRIPTION

       The showq daemon reports the Postfix mail queue status.	It is the program that emulates the sendmail `mailq' command.

       The showq daemon can also be run in stand-alone mode by the super-user. This mode of operation is used to emulate the `mailq' command while
       the Postfix mail system is down.

SECURITY

       The showq daemon can run in a chroot jail at fixed low privilege, and takes no input from the client. Its service  port	is  accessible	to
       local untrusted users, so the service can be susceptible to denial of service attacks.

STANDARDS

       None. The showq daemon does not interact with the outside world.

DIAGNOSTICS

       Problems and transactions are logged to syslogd(8).

BUGS

       The showq daemon runs at a fixed low privilege; consequently, it cannot extract information from queue files in the maildrop directory.

SEE ALSO

       cleanup(8) canonicalize and enqueue mail
       pickup(8) local mail pickup service
       qmgr(8) mail being delivered, delayed mail
