Dúvidas no SENDMAIL

[Estanis]

Pessoal. Sou novato no Sendmail to com as seguintes dúvidas.


Utilizo o Slackware com Sendmail

tenho recebido muitos emails no root "/var/mail/root" do seguinte tipo:

550 5.1.1 <[email protected]>... User unknown
<<< 554 5.5.2 No valid recipients
*********************************************************************

Recebo um email desses a cada 40 segundos pelo menos. Tive que redirecionar pra uma conta e baixar os emails na minha maq pessoal pra nao estourar as o tamanho da partição.

Pra vocês terem ideia, de ontem a noite pra hoje, tem mais de 3000 :| e-mails desse tipo.

Por sugestão de um amigo, dei uma olhada no ORDB.org pra testar se estava com relay aberto. Parece que não, pois me responderam o e-mail abaixo

*************************************************************************
This is an automatically generated email

The host you submitted at ORDB.org (meu IP), has been thoroughly
checked, and does not seem to permit relaying.

Please note however, that this may be caused by extreme delays at
the servers end.

Should we at a later time receive one of our testing emails from the
server you submitted, you will receive another email, telling you that
the server is in fact an open relay. In that case, please disregard this
email.

If you know for a fact that the host you submitted is
an open relay, please resubmit it via http://www.ORDB.org/submit/.
Additionally, some administrators have been known to block our ip-address
in various firewalling devices, which may also cause our test to fail.

If your host was marked as an open relay, it has now been removed from our
database, and will be removed from the relays.ORDB.org-zone during the next
zone-rebuild.

This email is sent from an unattended mailbox, so please do not
reply to it. To find information about how to contact ORDB.org,
please visit http://ORDB.org/contact/.

Have a nice day, thank you for using ORDB.org

PS. Need this mail translated? Have a look at:

Os emails continuam a chegar sem parar. verifiquei meu arquivo /etc/mail/realy-domains e está assim:

***************************************************************************

*************************************************************************

Minha dúvida é se as linhas que comçam com * permitem que todos que estejam nesses dominios utilizem meu servidor pra enviar e-mail.

Agradeço atenção de quem puder me ajudar a resolver isso. Tive que limpar na mao a fila do /var/spool/mqueue pq tava crescendo demais e simplesmente travando o SMTP.

Mas o problema continua. Isso foi só um paleativo que arrumei.

é provável que o que vc esteja vendo sejam os retornos dos zémail que um spammer tá mandando por seu intermédio (não vou jurar, contudo).

vários testes - bons - aqui:

faça o teste, antes de cair nas listas-negras.
