qmail+jbuce patch--DNS messed up?

[Peter Green]

My problem is specific to qmail-1.03 patched with jbuce. It seems to be
rejecting mail where the sender domain has a valid MX record but no IP
address. (One example is hotoffice.com.) Can anyone say what may be
happening? Are there better patches I could be using to deter spam,
increase logging, &c.?

Thanks for any help/pointers!
