Hi,
I've got a few questions:

1. where can I find out what all the variables like uri, myself, etc., mean?
2. how come is_domain_local($ruri) has a different result than uri==myself?
In particular, I have my external IP address defined as an alias. I.e.:
alias=4.2.2.2
When I say if( ! is_domain_local($ruri) ) when $ruri = user@4.2.2.2, the check succeeds.
When I say if( ! uri==myself ), the check fails (correctly, I think).

Thanks,
Mark Price
