If you want to do this, which is probably a reasonable thing to do,
you probably also want to make sure that you're not finding the magic
string in a comment line.

So, perhaps make it be

	egrep '^[^#]*/postfix/' /etc/mailer.conf

It could also be a reasonable idea to use the -c option, and check
that there is more than one (probably at least about 3 or 4) postscript
lines in there before starting - or better check that at least the
"sendmail" line is there

	grep '^sendmail.*/postscript/'

There's also no real need for a subshell there, use { } for grouping
instead of ( ) and start it on the same line as the || and avoid the \
(the other two \'s aren't needed in any case).
