I've had this once or twice and found that the problem is a combination of the constant reallocation of IPs by Cable/xDSL operators and blacklists. Someone using the same ISP as you has been found to be, or in some cases just been accused of, running an open relay, which is now on a blacklist. I just did "service adsl restart" got a new IP and resent with no problems. Perhaps in the future a responsible ISP may break the mould by running a check for an open relay immediately after allocating the IP. If the test shows positive, send a message to the account to that effect and disable it, then a large number of badly configured machines would be found by the ISPs and not the spammers. A side benefit to this could be that spam would be reduced dramatically overnight. One can dream. -- Dave Cotton <[EMAIL PROTECTED]>
