Here's the story, the other day I tried sending an email from my office to my linuxmail.org account. A little later I received an email saying: This is the Postfix program at host neuro-logic.com. I'm sorry to have to inform you that the message returned below could not be delivered to one or more destinations. For further assistance, please send mail to <postmaster> If you do so, please include this problem report. You can delete your own text from the message returned below. The Postfix program <twn2@linuxmail.org>: host linuxmail-org.mr.outblaze.com[205.158.62.134] said: 554 EMail from mailserver at 4.3.812.158 is refused. See http://spamblock.outblaze.com/4.3.812.158 (in reply to RCPT TO command) So I contacted the company which ended up being abuse.nl.easynet.net and told them that my company has this IP and we're not sending spam. I later get a reply from them saying: Please provide us with at least one of the delisting criteria outlined at http://dynablock.easynet.nl/errors.html. Neither www.neuro-logic.com nor any of neuro-logic.com's mail records point to this IP address, and 4.3.812.158 points to 'lsanca1-812-158.lsanca1.dsl-verizon.net', which is a generic DSL IP address, not different from Verizon's dynamic IP pools. Now, my ISP, Verizon, allows me to use a mailserver. It's not a real mail server, but what I do is use fetchmail to get mail from my webhost then download it to my mail server at the office. Outgoing mail is also sent through my mail server. So I guess they can't see my IP. Does this make sense to anyone? How do I get these yahoos to drop me from a spam list?? Thanks for the input.
