Hi list, Recently I have a problem and I don't know how to troubleshoot it. The error seems to be with procmail to cyrus-imap as shown in the error below:
Folder: (formail -r -I"Subject: Delivery failure notice" \ -A"X 180663 procmail: Error while writing to "/usr/libexec/cyrus/deliver-wrapper" B6ut it keeps on trying to send to the MAILER-DAEMON@<mydomain> until the load average went up to 3. I've already set the MAILER-DAEMON to a real mailbox and usually that mailbox can receive delivery failure notices. I've checked that the mailbox is not overquota (way below quota). How do I troubleshoot on the problem? All I can do is to look at the log, but I don't know what causes the Error while writing to "/usr/libexec/cyrus/deliver-wrapper". It happens after a few days of running the mail server (and it works as intended for those few days). Thank you.
