Hmm, maybe I am reading this wrongly (exim 4.67), but isn't verify.c:2798 if (dns_basic_lookup(&dnsa, query, T_TXT) == DNS_SUCCEED) only executed if the DNS request for the dnsbl succeeded: verify.c:2672 if (cb->rc == DNS_SUCCEED) ? > You can heavily modify the behavior of the resolver as laid out in the > manual. > > http://www.exim.org/exim-html-current/doc/html/spec_html/ch40.html#SECTmorednslists I read that, but as far as I can see, this only allows one to specify what TXT record lookup will done, it doesn't say anything about preventing this lookup altogether... -- ## List details at http://lists.exim.org/mailman/listinfo/exim-users ## Exim details at http://www.exim.org/ ## Please use the Wiki with this list - http://wiki.exim.org/
