Re: Devilish: Forget about DNS

After spending 20 more minutes to think about I'd go somewhat
more into detail:


If wanting to fetch the record for   somedomain.com

do a DNS query for  A, SRV and TXT record (or ANY) on


_lmap.somedomain.com     (violates the SRV RFC a little bit, but
                         for sake of efficiency)



If a SRV record is found then
  
   try the servers as described in the SRV records

elsif A records are found then

   try on of them or one after another, Port 80

else

   error, no record available.

end


If TXT record available then

  run it through maxcro expansion for sender name, IP address, 
  MessageID,...  and take this as the URL to query.
  (if macro after first '?' then protect special characters as
  usual in URL query parameters)

else

  use default URL  /_lmap/somedomain.com

end

-> Fetch record and evaluate
