It *is* a good idea. You just can't cheap out on configuring it. Ideally, your backup MXs should be configured with all the same capabilities as your primary MX - username authentication, SA, antivirus, RBLs, etc. - or they become an exploitable back door and a nuisance to the rest of the world. Spammers routinely target backup MXs first to try to take advantage of this. -- John Hardin KA7OHZ http://www.impsec.org/~jhardin/ [EMAIL PROTECTED] FALaholic #11174 pgpk -a [EMAIL PROTECTED] key: 0xB8732E79 -- 2D8C 34F4 6411 F507 136C AF76 D822 E6E6 B873 2E79 ----------------------------------------------------------------------- People seem to have this obsession with objects and tools as being dangerous in and of themselves, as though a weapon will act of its own accord to cause harm.
