Could you please clarify this? I tried using the same name(with @domain.com) and password as I use to get into Cpanel, and it didn't work. Where do you specify the name and password that SquirrelMail is supposed to use?
Thanks, Turtle. I tried again before I saw your post and it works now--must have mistyped something. But I went into spam filtering in options and I see this message: "WARNING! Tell your admin to set the SpamFilters_YourHop variable." Now what should I do?
