bypass_spam_checks_maps format - bypass single address

[MV via amavis-users]

I'm trying to make sure email destined to one particular account is
never spam checked, but I'm not sure about the bypass_spam_checks_maps
format
This is my config

# Begin
@bypass_spam_checks_maps = @spam_lovers_maps = ({
    "unsubscribe\@$mydomain" => 1, # bypass
    "." => 0, # spam check everyone else
});
# End

Considering that neither bypass_spam_checks_maps nor spam_lovers_maps
are overridden within amavisd.conf
I'd expect to bypass the spam check for any email destined to the
account "unsubscribe\@$mydomain".
Is this correct?

Thanks
