hmmm, do the headers from the email shed much light on what is going on?
They should at least indicate *where* the mail was held (and then released).
That should gain you a clue as to where to concentrate your search.

Could the spamming/sending just be coincidental?

Good Luck

I'm using Sendmail - possibly a bad choice, but it's what I have always

I check the maillog files.  The messages come in and within 1 - 10 seconds
are being sent to mailman.  I then check the mailman logs and I have no
errors (the error log is empty)  I have only a few bounces, and they are
from spammers.

Yes, I have the option for users to be able to receive mail as it comes in
or digest.  I also have it set that even if the mail does not reach the
minimum to automatically send out the digest, it should send it out once a
day.  But it's doing neither.
Now, being a physicist by trade I've started to experiment.  I can "spam" my
test list with a minimum of 53 messages and it will trigger something and
send out all messages for all the lists.  I tried it yesterday and it sent
all accumulated messages since the last time I tried this.  The amazing
thing is that the time and date stamp on all of the messages was the exact
time and day they were sent into the list!  So, rather than saying No. 13 at
3 PM, they said Nov. 11 at 2 PM and Nov. 10 at 10 AM, etc.

I also got digests to come out (don't ask me how) yesterday, and they too
were time and date stamped when they should've emerged - Sunday at 11AM and
Monday at 11AM, but I didn't get one for Tuesday! Even if no messages were
sent, I should get an empty digest.

So, now I'm really confused.  I checked the que in mailman and it is empty.
I hunted around in sendmail, and there is no apparent delay set.  There are
no locks set in mailman.  I have no errors in the logs.

What could be causing the delay?  And, why is it (sort of) removed when I
"spam" a list?

(I asked the UNIX/Linux guru on our campus, and he also had no idea.  He and
I spent several hours checking the log files.)
