[Mimedefang] Timeout on large attachments

[Mickey Hill]

Hi David, everyone,

Maybe you have answered this before, but I can't find it in the
archives.  Can you tell me exactly what is happening here, and perhaps a
solution?  This only happens on large ( > 10-20 MB) messages.  Thank
you!

INPUT_MAIL_FILTER(`mimedefang', `S=unix:/var/run/mimedefang.sock, F=T,
T=S:300s;R:300s;E:5m')

*** Side note: Anyone know where I can find the syntax/definition/man
page for this line?  And is 300s the same as 5m, as it would appear to
be to the (untrained) eye? ***

sub filter_begin {
...
    if ((-s "./INPUTMSG") <= (100 * 1024)) {
...
    } else {
        action_add_header("X-Spam-Not-Checked",
            "Messages over 100K not checked")
    }
}

sub filter {
    # No virus scanning here
    return action_accept();
}
