There%26#039;s several things that can go wrong.

1) The servers that your mail server is on send out a lot of spam mail. You may not be spamming, but others on the cluster of servers your mail server is on could be. Yahoo will assume you are just another spammer and send your messages to bulk.

2) Your e-mail doesn%26#039;t follow proper formats like proper headers. That raises a red flag and your e-mail gets sent to bulk.

3) Your e-mail looks like spam (you didn%26#039;t type viagra repeatedly or something like that right?).
