> I happen to use a mail server that is less forgiving (Courier), and every now and then I cannot send a mail due to this. It’s rare, but it does happen. If your mail server has such a configuration you may not receive some legitimate e-mails.
Why not fix Courier? Seems easier than trying to convince others to change how they configure their DNS. Be forgiving in what you accept and disciplined in what you send.
