E-Mails appeared to be jammed somewhere

    Hi, we're running SBS 2003 SP1 with Exchange SP2. We have about 50 email
    users, 20 of which are remote (RPC over HTTPS).

    I restarted the SMTP and Information Stores services a couple of days ago
    and within an hour lots of users were receiving NDRs from emails they had
    been sending over the last few months. A few of our main contacts then rang
    to say they had received up to a hundred emails that they had never received
    before. It appears that a lot of emails over the last few months did not
    leave the system, but it was never noticed because the majority of emails
    were going out OK. There doesn;t seem to be any common link between the
    emails e.g. sender, recipient, whether they had attachments or not. On the
    day we restarted those services I also noticed we had more or less hit the
    DB limit although no services stopped like they used to. I increased the
    limit in the reg. Any ideas?

    Thanks

    Hi Chris

    Thanks for replying.

    We use our ISPs smarthost. I have recipient (AD only) and imf filtering
    enabled so queues don't tend to get too big. Even if the queue did die, how
    would 85% of emails have left the system without any issues. I do keep an
    eye on the queues from time to time and I never noticed any great build up
    either. Strange one!

    Thanks

    wrote in message Are you sending via DNS or SmartHost? might want to consider SmartHost

    If you have implemented IMF, are you sending NDRs for those? typically
    spammers don't have valid email addresses, so your que just gets full and
    "quits"
