Hi everyone. SMTRPRcv requires CIDR notation to denote an entire IP range that you want to blacklist or whitelist.
The problem is, I am lousy at IP math. And every online CIDR calculator asks for things I *do not* have, like bits and masks and whatnot. I *only only only* know two things: the two IP addresses. That's all I know. So for example if I wanted to whitelist all Google mail servers, everything from IP a.b.c.d until IP w.x.y.z, then SMTPRcv would expect me to type in something like w.x.i.j / k Perhaps I misunderstand the concept. But isn't there an online (or downloadable) CIDR calculator that will take two IP addres, without asking for anything else, and give you the CIDR notation that describes that IP range? -- _/_/_/ Alfredo Jacobo Perez Gomez ([EMAIL PROTECTED] ) _/_/_/ _/_/_/ Home Page http://www.dreamworld.org/alfredo _/_/_/ _/_/_/ El Salvador / Costa Rica / San Francisco, USA _/_/_/
