** Using WeBWorK **

Thanks for that. Two more questions: can you specify login name, password and port on the server line, something like:

$mail{smtpSender}='mailserver.mail.com --login=myname --pass=mypasswod --port=11111'

or, if I'm using nullmailer, something like

$mail{smtpSender}=nullmailer

in which case the smtp sender points to a process, rather than a mail address?

Thanks again,
Alasdair
