We can't say a thing about version 'curent'. Please state full versions of spamassassin, Net::DNS and debian. Also, tell us how you installed spamassassin: are these distro packages or a manual install (if so: tell us how you did that). > > It is installed on a current version debian system. > We run a local nameserver using bind. > We invoke spamassassin via "spamassassin -t < testmail" where testmail > is a spam mail.

Please show values for: - dns_available - dns_server - clear_dns_servers - dns_local_ports_permit - dns_local_ports_avoid - dns_local_ports_none - dns_options - dns_query_restriction - clear_dns_query_restriction - rbl_timeout You can find the meaning of these (and many other) configuration options at: https://spamassassin.apache.org/full/3.4.x/doc/Mail_SpamAssassin_Conf.html Kind regards, Tom
