After resolving the POP slowdown issue with the help of some of the more
polite folks here, I have developed a new problem.
All mail that gets queued for delivery simply sits in the queue and doesn't
get delivered. It doesn't matter if the mail is for local delivery, or is
relay mail headed for a remote mail server.
What I am aware of changing: I added -R and -H to tcpserver's command line,
and I added my 10.x.x.x network to tcp.smtp.cdb. I can now deliver mail via
SMTP to rblsmtpd, and it does queue the mail, so I doubt the issue is in my
tcp connection rules.
I am accepting connections with rblsmtpd with the no-TXT-records patch, and
logging is being done by splogger to /var/log/messages.
There are no messages indicating anything related to qmail in syslog since
the issue began, except for one notation where rblsmtpd rejected a message
from a black holed site.
The line invoking rblsmtpd is (beware wordwrap):
/usr/local/bin/tcpserver -R -H -x /etc/tcprules/tcp.smtp.cdb \
-u 1004 -g 2108 0 smtp /usr/local/bin/rblsmtpd -r
blackholes.mail-abuse.org \
-r dialups.mail-abuse.org \
-r 'relays.mail-abuse.org:Open relay problem - see
<URL:http://www.mail-abuse.org/cgi-bin/nph-rss?%IP%>' \
/var/qmail/bin/qmail-smtpd 2>&1 | /var/qmail/bin/splogger smtpd 3 &
I can see messages queueing in /var/qmail/queue/mess/*, but they are not
delivered either locally or to a remote host (mail.swbell.net).
Through testing with other mail servers, I have determined that
mail.swbell.net is operating normally -- it both sends and receives mail.
I've sent test messages to my problem machine via mail.swbell.net and found
them in my queue, waiting for local delivery.
/var/qmail/queue/lock/trigger has permissions as described in LWQ.
The home directories of the users on the system are owned by themselves.
Some are world-readable, some are not. None are world-writable:

As I indicated, syslog shows noting useful. Just lots of me logging in via
SSH and su'ing to root. No qmail-related entries, save the rbl rejection,
since 4/30/01 at quarter past noon.
ps aux shows this (again, beware wordwrap):
root 242 0.0 0.2 1068 332 ? S Apr30 0:01

qmail-qstat shows this:
messages in queue: 311
messages in queue but not yet preprocessed: 310
make check runs ./instcheck; ./instcheck produces no output.
Running queue-fix produces no output other than that it's finished.
Please advise. Thank you.
