eu executo um servidor imap dovecot em uma máquina do ubuntu 8.04 (antigo, eu sei, mas não há chance de um upgrade em breve). De qualquer forma, tudo estava funcionando sem problemas até que eu reiniciei o servidor no outro dia e agora não podemos enviar e-mails através deste servidor. os clientes de email são todos mozilla thunderbird em máquinas windows. os e-mails baixam muito bem no thunderbird, mas quando tentamos enviar e-mails, recebemos uma mensagem dizendo login to server mail.mydomain e quando clico em digite nova senha ela continua falhando e exibindo o login to server mail.mydomain popup. quando clico em cancelar neste pop-up, então recebo a mensagem:
Sending of message failed. The message could not be sent using SMTP server mail.mailserverdomain for an unknown reason. Please verify that your SMTP server settings are correct and try again, or contact your network administrator.
Eu olhei em /var/log/mail.log e achei isso (o cliente thunderbird na rede de máquinas windows neste):

alguma ideia sobre como corrigir isso? Eu tenho acesso total ao servidor para que eu possa fornecer informações a partir dos registros, se necessário.
