How does your receiving MTA determine what is a valid local user at point of delivery? LDAP lookups? Do you mind providing technical details? What MTA are you using? Your right, it would have stopped most of the issues, but the sheer volume of mail we were receiving would have meant that the lookup themselves would have possibly been an issue. Definitely less of one than actually accepting it, even if we were >/dev/null'ing them though. cheers, Spencer. Bojan Zdrnja said:
Your server should reject it immediately (without accepting/queueing the e-mail). This means that the burden of NDN is on the remote server.
