Mas obrigado mesmo assim.

Pessoal, hoje depois do almoço o pessoal começou reclamar que não estava conseguindo enviar e-mail, tanto pelo
cliente de email (outlook) tanto pelo webmail. Estava vendo os processos ativos e me deparei com várias instâncias
do processo qmail-scanner-queue.pl e do qmail-smtpd.

Eu reiniciei o servidor, de momento resolve mas depois de poucos minutos ele volta acontecer o mesmo problema.
O recebimento de email está ok, o problema está no envio.

Aqui tenho um link que 1MB que está no gargalo, já estão providenciando um upgrade para 6MB, acho que até dia 20
o novo link estará funcionando. Não sei se isso pode influenciar.

Estou monitorando e os processos hora diminuem, hora aumentam. Mas o envio de e-mail continua parado.
Se alguém tiver alguma dica.

Obrigado...
