    We have begun to see the following issue occur, has anyone else?

    By doing telnet to our mail server and performing the standard helo commands etc the mail server takes the message no matter what. This is true even if the intended recipient is not a valid user on the system. Has anyone else seen this problem. We feel that the mail server should not take messages (No such user) if the intended recipient is not valid on the local system. These messages fill up our message queue as you can imagine as all messages are accepted.

    Note: These messages never get delivered they just sit in our queue.

    === example ===
    250 Hello
    mail from: -Fake from user
    250 OK
    rcpt to: - Not Valid on our system.
    250 Accepted - Still takes the message
    354 Enter message, ending with "." on a line by itself
    This is a test
    250 OK id=1IIXt5-00058I-6k
    === example ===

    In the mainlog I get..

    Do you have catchall turned on? if so, then the system is doing exactly that - accepting all.
