Yes, DCC whitelisting affects `dccm -B`. sendmail whitelisting can affect dccm filtering by sendmail.cf macros, such as by the misc/hackmc script in the DCC source. I do not know whether the sendmail "spamfriend" access_DB entries affect sendmail DNSBL filtering. If you do try `dccm -B`, it might be prudent to omit the /var/dcc/whiteclnt "option dnsbl-on" line for a few days and instead use an "option log-all" line and watching the /var/dcc/log files to see what would have been rejected. Note that `dccm -B` also checks the IP addresses of MX servers for body URLs and envelope names in the DNS blacklist. I've found that effective. I use this setting in /var/dcc/dcc_conf: DNSBL_ARGS="'-Bset:rej-msg=5.7.1 550 mail %s from %s rejected; see http://www.spamhaus.org/xbl/' -Bsbl-xbl.spamhaus.org,any" Vernon Schryver [EMAIL PROTECTED] _______________________________________________ DCC mailing list [email protected] http://www.rhyolite.com/mailman/listinfo/dcc
