Sorry for my english. I´ve got a big trouble with my server FC4. I´m not able to recieve any email from yahoo, and I can send mail from my domain. No "ERROR" not, no delivery e-mail in yahoo box. imapd and pop are configurated. Please somebody know what I´m doing wrong??. Thank you very much for your attention and for being merciful with my poor english.
Do you receive emails from other domains than Yahoo? Then it might be that you're on a Yahoo blacklist or don't have proper PTR or SPF records. Is your server on a DSL line with a dynamic IP address?
Thanks Falko¡¡ Thank you very much for your attention¡¡ At the end we´ve changed router. And by the moment works smoothly (we are crossing our fingers). We´ve got DHCPD. Sometimes we´ve got troubles with port 25. We´ve not received no yahoo, no hotmail, no gmail, nothing from out of our domain. I don´t know why but always we´ve got problems with incoming mails. We reconfigurated, we changed netcard,...As you can see if is not one problem is another.... By the moment, it works,.... I´m very thankfull for your attention¡¡ Nice meet you¡¡¡
Then you should check if you're on a blacklist. This is quite likely if your server is on a dynamic IP address.
