    I know I wasn't suggesting that, but to be clear:

    20050622

             Cleanup: the DNS lookup code now accommodates name server
             replies longer than 4 kbytes, with a hard upper limit of
             32kbytes. For safety reasons, the number of MX host addresses
             that the SMTP client will try was reduced from unlimited
             to just 5, so that Postfix won't spend forever trying to
             connect to dozens and dozens of bogus MX hosts. Files:
             dns/dns_lookup.c, global/mail_params.h.
