I have been using 2 or 3 domain name e-mail addresses for years now but recently I wasn't getting any replies to mail that I sent.

I sent an e-mail to my dad over the weekend (He's on BT Yahoo Broadband) but he never received it. So, I sent the same again from 3 different domains. He didn't receive them either. I asked about his Outlook spam filter and he said that it was enabled but it filtered into a junk mail folder rather than deleting them so he would have seen it in there. I told him to log in to Yahoo webmail and check that. Sure enough, the spam filter was enabled by BT Yahoo and all of my mails were in the junk folder.

* So, why, all of a sudden have my domains been classed as spam e-mailers?
* How to I get my domains lifted from any blacklists?
* What's the point of sending any e-mails if you don't know if the recipient is ever going to get them?

Maybe another reason why people register and never post - they don't receive a confirmation e-mail from the site.
