Apparently I'm not supposed to reject email when there is no reverse PTR record. Can I have my Perl script add a line to the email headers that says essentially, reverse resolution failed? I'm using iptables QUEUE on SMTP connection packets. What I'm asking is, what is the extent of what I have to work with? If I have headers, how do I access them to change them? I know I can grab the destination and source IP addresses, but do I have email headers yet? Maybe I should just query a list of IP's which don't reverse resolve that I should relay, a white list.
Is there a Perl module that will allow me to query DNS blacklist servers? If so, what is the module called and which DNS blacklist server do I want to query? _______________________________________________ PLUG mailing list [email protected] http://lists.pdxlinux.org/mailman/listinfo/plug
