Make sendmail queue emails to a domain
I'm trying to make sendmail put all emails addressed to yahoo.com recipients into a special queue group which are delivered at a slower rate than normal to keep yahoo.com calm about spam.
In my sendmail.mc I've used:
FEATURE(`access_db',`hash -T<TMPF> /etc/mail/access.db')dnl
QUEUE_GROUP(`yahoo_com',`P=/var/spool/mqueue/yahoo.com, I=2, J=5')dnl
Then I added a "QGRP:yahoo.com yahoo_com" line to /etc/mail/access, used "makemap hash access <access" to generate access.db, and "service restart sendmail".
All the directories exist, are owned by root, and have permissions 0700.
mailq says those queue directories exist but are empty.
But it still seems to send all email addressed to yahoo.com recipients immediately. I know it's seeing my settings in sendmail.mc because I received several sendmail startup errors when I did things in the wrong order, bad paths, and so on. It's as if it simply isn't trying to queue emails.
The only thing that may be defined wrong is it may not be seeing or able to use /etc/mail/access.db, because I tried to deliberately misspell that name and there was no error when I restarted the daemon.
Is there some additional sendmail.mc option I need to use to enable queueing, or some option I may have inadvertantly used which disables queueing?
I'm running FC4 and sendmail 8.13.
