OK, I don't doubt you on that score. 16 addresses for the price of one on a DSL line is nothing to sneeze at. Possible solutions: 1) Will they delegate your block to you, using the classless delegation rules? The details of how this works is in RFC 2317, available from <http://www.faqs.org/rfcs/rfc2317.html>. 2) Can you put your mail server on the same machine as one of your dns servers? Since they've given you PTR records for those, you could conceivably use one of them for mail as well. You'd have to use whatever name is in the PTR record for the name of the mail server, though. Also, I'd investigate the possibility that the fault lies not in your reverse DNS setup, but in your mail server's setup (either the mail server setup itself, or in one or more of the domain records that are used in mail delivery). Can you tell me the name of the domain and the name of the mail server? ____________________________________________________________________ Chris Buxton Men & Mice cbuxton@menandmice.com http://www.menandmice.com
