Mail Failure

[Orogan]

I have had problems with mail, basically when the user clicks into the mail it leads them to home.php, after they login again the users click onto mail and it leads them to the mail page.  I am not sure exactly what this is, any help?

So it is   X.php-->mail.php=home.php-->X.php-->mail.php

you use a module that does not "allow anonymous"

that is not a problem of  the core =)

install a fresh vanilla +nb and tell me if you have these problems too. I have them not.
From what you describe, you break your allowed navigation by NOT HAVING in a mail module the allow_anonymous set.

Your module, your problem.
