Do:

$ ls -lZ /path/to/file

and you will see the file's current SELinux context (amongst other 
information). Let's say it's "system_u:object_r:usr_t".

Dan suggested changing context type to "httpd_squirrelmail_t", which 
would give your file a context of "system_u:object_r:httpd_squirrelmail_t".

You could change it back using:

# chcon -t usr_t /path/to/file
or:
# chcon system_u:object_r:usr_t /path/to/file

See "man chcon" for more details.
