Hello Courier Users,

I have a user whose mail frequently triggers the following log message:
postfix/pipe[7826]: 14E261295F1: to=<<URL:mailto:u...@example.com>u...@example.com>, relay=maildrop, delay=2024, status=deferred (temporary failure. Command output: maildrop: Timeout quota exceeded. )

Something that gets executed from this recipient's maildrop recipe gets hung to stuck.

maildrop has no choice but to abort mail delivery.

When stracing a long running maildrop process, maildrop seems to go through the user's entire mailbox bouncing stat64 calls off files.

stat64("/PATH_HERE/mail/.Archive Old Emails/cur/<URL:http:// 1443112974.M868311P11219.imap.example.com: 2>1443112974.M868311P11219.imap.example.com:2,", {st_mode=S_IFREG|0600, st_size=29403, ...}) = 0

Unless this process takes several minutes, this isn't the issue. You need to strace everything, until the timeout occurs, and then look at what was going on before the timeout. strace has a useful -t option that logs timestamps.
