 Just treat it like a pseudo-regular expression. [45]xx stands for a
 three digit SMTP reply code as defined in RFC 821 Appendix E. Go to
 www.faqs.org to read more about RFC 821. You should not just make up
 your own error codes, but stay within the RFC.

 An error code starting with 4 is a temporary error, and the client
 is invited to retry. 5 signifies a permanent error.
