Yahoo mail has mis-labeled mail from my domain as bulk or spam. How can I get them to unfilter my domain?

Question

Someone must've reported that my system was an open relay. I looked into it and fixed the issue. Now I can't get yahoo to remove the filter. All my mail either goes into the bulk mail section of my reciepent's yahoo account or just disappears. How can I get them to check into this?

Answer 1

1.) Contact Yahoo and tell them this (good luck, they probably won't change a thing)
2.) Find out what spam filtering software Yahoo uses and contact that company (see #1)
3.) When you're signing people up for e-mail notifications / newsletters, make a point of telling them to add your address to their friends list - this bypasses most spam filters.
4.) Consider taking another look at your security.
5.) Consider getting a different domain name.
