Hi, please feel free to do a local override of the macro. How to do this is explained in the package docs. Andreas might revise the default in the package, if it were my decision, I wouldn't change this, even if in these days where explicit SMTP routing is not even used any more by spammers.
Please also note that it is clearly documented that this rule blocks addresses that are RFC-valid.
