Eu corri um chmod 777 * na minha pasta pessoal. (Eu sei, eu sei. Eu nunca farei isso novamente.)
Desde então, fetchmail parece estar quebrado.
Eu o uso para buscar mensagens de uma caixa de correio do Exchange 2003 por meio do DAVMail e do OWA.
O problema é que fetchmail reclama de uma "incompatibilidade de expunge" sempre que recebo uma nova mensagem. Exclui a mensagem da caixa de correio do Exchange, mas nunca a encaminha. Parece haver um problema no processamento de correspondência, mas não consegui identificar onde.
Qualquer ajuda seria apreciada.
Aqui estão os arquivos de configuração relevantes.
~/fetchmailrc :
set no bouncemail
defaults:
antispam -1
batchlimit 100
poll localhost with protocol imap and port 1143
user domain\user password Password is root
no rewrite
mda "/usr/bin/procmail -f %F -d %T";
~/procmailrc :
:0
* ^Subject.*ack
| expand | sed -e 's/[ ]*$//g' | sed -e 's/^/ /' > /usr/local/nagios/libexec/mail_acknowledgement
~/.forward :
| "/usr/bin/procmail"
E aqui está a saída quando eu corro fetchmail -f /root/.fetchmailrc -vv :

Se alguém encontrar esse problema, a solução foi embaraçosa.
Nós clonamos a VM do Ubuntu na qual o fetchmail estava sendo executado periodicamente. Como resultado, as tarefas cron responsáveis por buscar mensagens estavam sendo executadas simultaneamente, em ambas as máquinas.
Isso é o que causou os estranhos erros de fetchmail que eu estava vendo, pois dois clientes estavam buscando o mesmo e-mail exatamente ao mesmo tempo.
