1: create multiple admin accounts
Serious bug,for example,there in only one account,admin,it can delete itself,once you delete,you can never login!(For example,delete by mistake) For new create account,also can delete other administrator account,not safe!It needs to fix.

2: ignore RBL lookups for well known domains
Is it buildin function? where can i set no check RBL domains?

Tommy,

Comment 1: Do you think Xeams should prevent users from deleting the default admin account? I am sure, some users will disagree with that approach. In any case, if you mistakenly remove every account, add one back in before logging out. In the worst case scenario, you can always reset the password using instructions on https://www.xeams.com/ResetPassword.htm

Comment 2: There is no configuration for this. It's built-in.
