"sendmail configuration using m4 on a Cobalt Raq3 (long)". I successfully got the ordb.org rbl working per the post. I tried adding the spamcop rbl and everything fell apart. Here are my quesstions and problems. I have searched the archives, sendmail.org, ordb, spamcop but can't find anything or anyone mentioning if multiple FEATURE lines with rbl options are okay. If anyone has any info on this or a sample redhat.mc, tech doc, archive link, I would appreciate it. I am just trying to get Spamcop and ORDB
I had both relays.osirusoft.com and bl.spamcop.net running on our Qube3 (sendmail 8.10.2) for several months; I finally ended up taking off bl.spamcop.net because I had too many problems with it blocking various irate contractors. I don't think the issue is with sendmail objecting to the multiple FEATURE lines (at least not with 8.10.2), but my SWAG might be that with two DNSRBL lookups you may be getting a lot of timeout errors.
Not really related to your question, but judging from the stuff getting through relays.osirusoft.com (and getting tagged by Spamassassin) on our system, I think more and more spammers are avoiding the open-relay specializing DNSBLs like ORDB by going for open proxies instead. Has anyone else noticed this? We haven't been rejecting any more mail than "usual" (see <http://bluebird.sinauer.com/~morse/spam_chart.htm> for the sorry tale) but I'm seeing more Spamassassin-tagged messages in my inbox and reporting them to Spamcop.
