Host not found - Problemas ao receber e-mails de um determinado domínio
Olá a todos.
Venho através destas mal traçadas linhas expor mais uma dúvida que consome minhas horas de sono e beleza! :sleep:
Tenho um servidor postfix, o qual eu configurei, e este está recebendo e-mails do gmail, yahoo, hotmail, etc...
Dei uma pesquisada na net mas nada tao específico quanto ao meu caso.
Contudo um usuário não consegue receber e-mails de um determinado dominio:
Citação:
Mar 13 15:03:26 labbi postfix/smtpd[8178]: connect from mtomsw5.effem.com[193.38.170.133]
Mar 13 15:03:27 labbi postfix/smtpd[8178]: NOQUEUE: reject: RCPT from mtomsw5.effem.com[193.38.170.133]: 450 4.7.1 <mtomsw5.mto.na.mars>: Helo command rejected: Host not found; from=<
[email protected]> to=<
[email protected]> proto=ESMTP helo=<mtomsw5.mto.na.mars>
Dá o erro "
Host not found". Só que eu não sei se erro provem do meu servidor ou do cara que está tentando enviar o e-mail.
Abaixo a o meu main.cf:

Eu comentei as diretivas na secão ##Anti-SPAM##, achando que estas diretivas estivessem dificultando demais o recebimento dos e-mails (se bem que a funćão dela. :p) Contudo nada mudou...
Vale ressaltar que eu uso o postgrey, spamassassin e amavis.
Ab, Duca.
