Jammer.

Intussen heb ik in de loop der tijden dit lijstje in mijn main.cf, geen idee of dit intussen de meest ideale configuratie is.

reject_rhsbl_client blackhole.securitysage.com,
reject_rhsbl_sender blackhole.securitysage.com,
reject_rbl_client sbl-xbl.spamhaus.org,
reject_rbl_client blackholes.easynet.nl,
reject_rbl_client cbl.abuseat.org,
reject_rbl_client proxies.blackholes.wirehub.net,
reject_rbl_client bl.spamcop.net,
reject_rbl_client opm.blitzed.org,
reject_rbl_client dnsbl.njabl.org,

Wat hebben jullie staan?
