Você configurou o DNS reverso corretamente? Certifique-se de que os registros de avanço e reversão de seu servidor de correio correspondam.
Eu instalei recentemente um servidor de email postfix + dovecot + dkim multi domínio, multiusuário, multi alias no meu sistema debian squeeze. Tudo funciona, exceto por um grande problema que basicamente torna a coisa toda inútil:
Todos os e-mails enviados pelo meu servidor vão direto para o spam. (gmail, hotmail)
A primeira coisa que fiz foi fazer o conhecido teste allaboutspam e tudo está marcado (verde), exceto pela coisa BATV (amarela):
Reverse dns: green
HELO Greeting: green
RBL: green
BATV: yellow
SPF: green
DKIM: green
URIBL: green
SPAMAssassin: green
Greylist: green
Estou muito confuso e não consigo encontrar uma maneira de resolver esse problema. Pergunte-me qualquer detalhe se você precisar.

Você configurou o DNS reverso corretamente? Certifique-se de que os registros de avanço e reversão de seu servidor de correio correspondam.
O Gmail lhe diz:
Why is this message in Spam? It's similar to messages that have been detected by our spam filters.
Isso geralmente é um problema com conteúdo com aparência de spam.
