Finally got email server set up, questions about sending.
Alright I have a domain with dyndns.org and have an MX record through it so I decided to set up an email server on my server. I followed this guide, http://forums.gentoo.org/viewtopic.p...asc&highlight= so a quick glance would show the full setup. Basically I recieve mail at email@example.com and can now send to a couple locations (hotmail, my account on my friends server). But after I got this all set up I tried sending mail to an AOL account and had no luck. That's when I started reading about how a lot of providers don't accept email from servers like mine, they see them as open relays and spam. Then I followed the part in the guide about having it go through my ISPs SMTP server before it hits the net, and its still causing problems. The address even got banned from my ISP when I tried to email my account on there, I got this link in a failed delivery notice http://security.rr.com/mail_blocks.htm#security So basically I'm not sure what to do. I've been reading on some sites like http://spf.pobox.com/faq.html about ways to prevent this but none of them seem to be helping. I don't want to have to send through my ISP because to me that kind of defeats the purpose of having your own email server. If anyone has done this before and can give me some advice or some links I'd appreciate it greatly.
