    Thanks Wietse,

    Actually I think that none are from our system.
    grepping gave me a few from other systems (12 out of
    ~3400 and growing...)
    BTW the maillog does not seem to show anything
    interesting. The "messages" files has the following
    once in a while:
    Feb 8 05:24:03 mail amavis[6701]: (06701-03) (!!)
    TROUBLE in check_mail: spam_scan FAILED: timed out
    Feb 8 05:24:03 mail amavis[6701]: (06701-03) (!)
    PRESERVING EVIDENCE in
    /opt/zimbra/amavisd/tmp/amavis-20070208T050943-06701

    Can Amavis be "holding" the queue?

    Thanks again, Eric
    P.S. Postfix is one hell of a system! You did an
    amazing job!!!
