That is incorrect. There is always one argument that follows the -d option,
even when that argument is a zero-length string.
So, it would appear that something is messing up the argument vector.
Besides, Postfix does not accept mail for the zero-length address.
Perhaps you have some aliasing rule in place that produces null
string results.
