I seems they are:

    src/showq/showq.c:
        ...
        case REC_TYPE_FROM:
            ...
            quote_822_local(printable_quoted_addr, start);
            printable(STR(printable_quoted_addr), '?');
        ...

        case REC_TYPE_RCPT:
            ...
            quote_822_local(printable_quoted_addr, start);
            printable(STR(printable_quoted_addr), '?');

So unless that's "relaxed", with the responsibility moved to
postqueue(1), relaxing the rules in "postqueue" is perhaps futile.
