Olá pessoal,

Estou com um problema em um servidor que assumi a pouco tempo. Não sou íntimo do postfix mas preciso aprender agora.

Aqui o envio das mensagens começou a ficar lento e agora parou de vez. Tentei as verificações básicas mas não encontrei a causa.

O log diz:

Não compreendo esses erros, alguma dica para solucionar ?
