Problem: submissions of articles being rejected -- sometimes

[Lynn D. Maas]

I am a novice at using innd, nntp, etc. and I have a problem with innd
(or nntp?) rejecting articles after a short time and then accepting some
and then rejecting some.  I have configured inn.conf (to the best of my
understanding of options) to not throttle messages.

Some background info:

o Redhat Linux 7.3
o inn 2.3.2
o Using libinn.a routines to submit articles via my own program.
o For development and testing I have all components running on the same
computer.

I had been running fine and had successfully submitted 80,000+ articles
to the news server from my program.  I moved my environment to another
computer (same software versions, config files, etc.) and now articles
are being rejected after a short time and then only intermittently
accepted.  I intermittantly (most times after ~50 articles) get the
rejected article error message

437 EMP rejected (f/s/l)

I have configured the inn.conf to prevent throttling by inn/nntp (I think).

I have attached my inn.conf file to this message.

Any advice or suggestions will be greatly appreciated.

Thanks in advance.
