Dear List, currently I ask ordb.org whether mail comes from an open relay. But this covers not all the known spam-sources. So it would be nice to have one or two other dns-based relay checks in my sendmail rules. So I have FEATURE(`dnsbl',`relays.ordb.org',`Rejected - see http://ordb.org/')dnl FEATURE(`dnsbl',`blackwholes.wirehup.net',`Rejected - see http://domea.wirehup.nl/error/erros.html')dnl set in the mc-file, I generate the sendmail.cf from. But It seems that sendmail only asks the first dns server and if this states the relay as "not known as an open relay" it accepts the connection. How do I get sendmail to do more relay checks? Thanks in advance Thom -- ------------------------------------------------------------------- bye bye (c) by Thom | Thorsten Marquardt | EMail: THOM@kaupp.chemie.uni-oldenburg.de | Member of the pzt project. | http://kaupp.chemie.uni-oldenburg.de/pzt -------------------------------------------------------------------
