The goal of selinux is to restrict unauthorized access of applications to
certain resources. This isn't accomplished by locking up the whole
system so you'd better look for errors somewhere else.
The information you provided is close to useless, don't expect anybody to
be able to help you. System logs, strace, etc should help identifying the
problem.

There are many ways of accessing a mailbox (imap, pop3, etc..). I guess
you want direct mailbox access.

You are trying to put a sechole into the system, that's why the MTA
corrects it. You have many choices though:
 * remove the scott_vandusen user and make it an alias to point to scott.
 * forward scott_vandusen's mail to scott.
 * same groups for both users with 0660, though this probably will
   not work because the mbox file usually has the MTA's group on it.
 * log in as scott_vandusen through imap/pop.
 * create a sudo script that will move mail from scott_vandusen to scott
   before scott's mail is retrieved (many MUAs have a feature to execute
   custom scripts before retrieval).
 * Change the uid/gid of scott_vandusen to scott's.

Probably the alias is the best solution unless there is a real
requirement for the two separate accounts.
