I have many errors of this type in my logs:
2 * postfix/pipe[21511]: BC8DD3356A: to=<*****@******>, relay=dovecot,
delay=1001, status=bounced (Command time limit exceeded:
"/usr/local/dovecot-1.0-rc2/libexec/dovecot/deliver")
My command time limit is 1000s in postfix (more than 15 minutes)
After many check, I found that a lots of this error is not really an
error.
The mail is delivered in the mailbox, but postfix send an error message.
Like if Dovecot LDA process dont exit correctly after sending a mail.
Do you know this bug ?
As workaround i set the command time limit to 1400s but this is too long
for our customer. They need in time service.
We use an NFS server as storage for all our mail.
