for this purpose.
OK, but if you have a `sendmail_path` set with `-f` in it, then won't you
eventually end up with a command line with two `-f` options? I don't see
how that could possibly work.
It seems like the only way you could get it to work would be something
like this:
{{{#!php
<?php
$phpmailer->isSendmail();
$phpmailer->Sendmail = '/usr/sbin/sendmail';
}}}
