This may be a really basic question...
What are the SMTP authentication settings on the Spry server?
I tried looking at the Exim settings in the WebHost Manager panel, and around the help files of this site, and I can't figure out basics, like what the port is (default 25?), or which login and password I should be using.
Up until now, at home I've been using my local ISP's SMTP server, so this never really came up.
But now I'm using a PHP script (PHPMailer) to email from the site, and I think the SMTP is refusing to send mail because I don't have the authentication right.
So... what do I need to know to send email from within PHP on Spry's servers?
