Erro postfix

Rafael Alexandre
Bom dia galera, tudo bem?

Estou com alguns problemas no servidor Postfix. Está dando o erro abaixo com frequência, o problema é que o erro é entre e-mails dentro da própria empresa e mesmo domínio.

O erro que acontece é: (host 127.0.0.1[127.0.0.1] said: 421 4.4.2 service timed out. (in reply to end of DATA command))

No log do e-mail aparece:

Oct 8 08:27:52 smtp postfix/qmgr[9285]: 63F603F8B60: from=[hidden email], size=49190, nrcpt=2 (queue active)
Oct 8 08:28:23 smtp postfix/smtp[24804]: 63F603F8B60: to=[hidden email], relay=127.0.0.1[127.0.0.1]:10025, delay=67092, delays=67061/0/0.04/30, dsn=4.4.2, status=deferred (host 127.0.0.1[127.0.0.1] said: 421 4.4.2 service timed out. (in reply to end of DATA command))
Oct 8 08:28:23 smtp postfix/smtp[24804]: 63F603F8B60: to=[hidden email], relay=127.0.0.1[127.0.0.1]:10025, delay=67092, delays=67061/0/0.04/30, dsn=4.4.2, status=deferred (host 127.0.0.1[127.0.0.1] said: 421 4.4.2 service timed out. (in reply to end of DATA command))

Desde já agradeço a ajuda.

Pessoal,


         Estou enfrentando problemas com SPAM no meu servidor e instalei
o SPAMASSASSIM e o mesmo está reescrevendo no assunto dos e-mails.   Ja
tem 3 dias rodando e está eliminando bem o SPAM. Gostaria agora de
descartar esses e-mails e pergunto:

É possível fazer isso pelo Dovecot (que está operando como lda)? Ou
preciso de algum script tipo um spamfilter.sh p/ fazer isso ? Segue
configuração   master.cf e local.cf(spamassassim)

master.cf

Você faz no dovecot. Basta ativar o sieve e criar um script padrão.
