Actually, there were a few single instances of this error outside of the 34

Yes, using softlimit to restrict process memory limit is useful, and in fact
necessary to prevent this remotely-exploitable vulnerability in qmail:
Hello all,
Recently, I checked the smtp log files of my qmailtoaster server, and found
millions of the following error message written to the smtp log:

We had an incident where both our local caching name servers stopped working.
They returned SERVFAIL (see example below). They were set as the

may never be queried" it leads me to
I noticed this Spamdyke error message:

Indeed this user's greylist directory is full:

A client using our Spamdyke-enabled mail server has reported someone sending

Thanks Sam.
BTW, I created a script to automate creating the custom sender configuration
files using the _ip_ and _sender_ directory structures:
Update: I added `reject-sender=none` to /etc/spamdyke.conf and these errors
started appearing in the log:
