if that makes a difference -- for example, add another zero (200M) and
retest. On my own server, softlimit is set to 80M.
Don't forget to restart the service after making the change. :)

Ok, That seems to have done the trick. I received an email from the client.
I bumped it up to 128M.
Thanks

Ron,
Can you do a little testing and see what's adequate? I expect that 128M
is a bit overkill. We'll need to get the QMT defaults bumped up a bit
depending on your results.
Thanks.

Don't forget that softlimit not only prevents misbehaving software from
running away and degrading the system's performance, but it ALSO
prevents resource starvation denial of service attacks.

Ok, I went in and extended the idle time out to 5mins and had her send
me another email.
Following is the log file that I got from that test:

I'm not concerned about the former, either. I pretty much exclusively
use softlimit to prevent the latter - DoS attacks.
The concern isn't about the NUMBER of concurrent connections - a
resource starvation attack can be done with very few, even 1 single
connection, depending on the
So instead of hitting the spamdyke timeout, it hit a timeout on the i/o
operation. Still doesn't point to the root cause. :(
Why softlimit doesn't issue some sort of error message is beyond me. I'm
still inclined to ditch it.
Thanks Ron.

I'd say that eliminates softlimit as being involved then. ;)
Everything seems to point to a bug in spamdyke. Dossy's post appears to
have a few clues.
