Title: Add new configuration option, to set sendmail params on phpmailer

With some hostings the sendmail doesn't work when you choose for mail type 'mail'. The phpmailer class adds by default some extra parameters and it works if these extras parameters are removed.

I think it's better to have something configurable in joomla! than modifing phpmailer class after each joomla! upgrade.
