Ticket #1483986 (Bugs) Session expires

Hi all,

While I won't claim that I have fixed *the* session expiry problem, if the lack of recent complaints from my users is any indication, I have fixed *my* session expiry problem.

Following up on a tip from Thomas, I disabled the rcmail_authenticate_session() function in /program/include/main.inc. As Thomas explained, this piece of code does a double check on a cookie dropped in the client as a security check. To disable it, I changed the "return $valid;" at the end of this function to "return TRUE;" and the complaints I had been receiving died just like that.

DISCLAIMER: While I don't recall changing anything else of significance around the same time, I might have. I have been poking around a little.... So while I *think* the above fixed the problem for me, someone else had better verify it.

..Bruce
