    I have for the second time reached a stage where exchange is dissapearing up it's own beginnings due to swelling SMTP queues which begin to bring down the server slowing it to a appoint where SQL server agent activities are slowed to a critical level
    I am following the lengthy and processor greedy routine to clear down the queues etc etc using the KB I obtained the last time it happened
    In a final attempt to save my sanity I ask for answers to the following thoughts (with the process I need to follow) which I want to follow to the end before I kill exchange for good
    1) is there a way NDR's being sent from my "" subject "delivery notice notification (failure) "can be turned off. The queue is only so big because exchange is relentlessly trying to send these back to senders who are spamming from cloaked aliase
    2) My Exchange is working with a webhost POP3 mail service and all incoming mail is collected from there (I think). I am assuming that somehow these spams are actually somehow being send direct to my server exchange system. can this be so? if it is, why cant I simply just turn this issue off either in Exchange or ISA. Surely there must be an 'only receive mail from the chosen POP3 boxes' option. I dont want mail coming from anywhere other than the seven POP3 accounts at our email server hos

    Scamps,

    So it does turn out that you had an SMTP open relay.

    Read this KB and the associated KBs at the bottom. Repost if you have issues
    following these instructions.

  4. By "un"checking the 'Allow NDR reports' in ESM - what is this actually
    doing? what affect does it have on current operations?
