Hi,
I've been running spamassassin forever and this has been bugging me for
probably a decade, across various versions of SA and RedHat/FedoraCore
Linux. Googling has produced nothing helpful and the problem has finally
annoyed me enough to join this list and ask the real experts...
Basically, I have a whitelist.cf file with about 2000 whitelist_from and
whitelist_from_rcvd entries in it. It seems that at some point into the
file, SA quits reading it, or is otherwise ignoring entries, such that
emails from "whitelisted" senders several hundred lines into the
whitelist.cf file are not being detected as whitelisted.
My quickie fix has been to move ignored entries to the top of the
whitelist file when I notice them. That reliably fixes the non-working
entries, but gets me no closer to a real solution.
Running --lint and --lint -D shows no issues.
Any ideas of what might be causing this, or further troubleshooting
steps to try?
My setup is currently a fairly plain-vanilla
spamassassin-3.4.0-13.fc21.i686 on Fedora Core 21. (Yeah, I know...
Migration to new server/CentOS is underway.) I'm running sendmail with
MimeDefang and a heavily customized mimedefang-filter script to feed
emails to SA.
Thanks for any help,
Charlie
