So then now instead of mail to misspelled domains, instead of bouncing, now goes to /dev/null and you have no idea that your critically important piece of information didn't get through? Neat. On Mon, Sep 15, 2003 at 08:17:43PM -0500, netmask wrote:

No, it accepts if the from domain exists - but only if it *REALLY* exists.
Anyone want to guess what happens to all those from addresses it captures?
No doubt.. It's unfortunate that they are running a daemon on port 25 on that box.. and that it actually lets you helo and mail from.. and not until you get to rcpt to does it reject.. unless you use a domain its now got cached in which case it accepts the to: and closes at data. (So, if you rcpt twice, it'll accept it.. cuz like everyone else, its own dns server resolves everything)
