For example, if you implement SPF on your own domain and then reject at the SMTP level accordingly you can whitelist your own domain.
That way you can still allow your users to not challenge each other.
With different SMTP servers you can reject email from your own domain unless it comes from certain IP blocks using something other than SPF.
SPF seems to work best for me though.

I had this same problem. Do not White list your domain only whitelist Valid email addresses in your domain you want mail from, Black List
your address, Face it with all the hotmail and other accounts if you want
to email yourself you have lot's of ways of doing it.
Just my 2 Cents.

I bet this is your problem. Spammers like to send messages that appear to come from your own email address.
