So what does the silly thing want? | |The correct way to send email is to relay your email to your ISP's |mail-server, and NOT send from your DHCP allocated address directly. |The FreeBSD lists require the incoming mail-connection come from an |IP-address which has a reverse IP entry for it, making it much easier |for them to track who has been abusing the lists. Well, correct is a subjective word. Let's just say it's the only option that hasn't been disabled by FreeBSD's mailing list server (I'm on tons of lists, and FreeBSD's is the only one I've ever had this problem on; all others treat the EHLO text as nothing special -- user-provided garbage potentially, which it is!). I prefer not to route all my e-mail through my ISP's mail relay because: 1) who that has much computer experience likes the phrase "single point of failure", and 2) relaying though the ISPs server makes e-mail snooping that much easier. Users inside corporate or government firewalls or on internal networks with internal DNS and mail relays that just relay the EHLO text (containing the internal-DNS FQDN; I have one of these at work) are locked out as well.
