I read the See http://dnsbl.njabl.org site, and found that the ISP is
bouncing some (but not all !??) messages because:
*aaa.bb.ccc.dd* is listed as a dial-up port / dynamic IP in dnsbl.njabl.org
Why would some messages be delivered, and not others? The client does
have DSL service, and does get a dynamically assigned IP address, but I
have DSL at home too, and my home workstation sends it's system emails
without any trouble.
Again, any assistance will be most appreciated.
