Hello,
I'm using 2.1.7 with seive and mysql quotas. We had an outage the other day where the database server where quotas are stored was not available for a short period of time.
In dovecot land, the following types of errors occured in that scenario:
Oct 26 22:19:01 grosbeak dovecot: lda(example@riseup.net): Error: Internal quota calculation error Oct 26 22:19:01 grosbeak dovecot: lda(example@riseup.net): Error: sieve: msgid=<20122132765181x.ABCCE457@example.com>: failed to store into mailbox 'Trash': Internal error occurred. Refer to server log for more information. [2012-10-26 22:19:01] Oct 26 22:19:01 grosbeak dovecot: lda(example@riseup.net): Error: sieve: script /maildir/e/example/.dovecot.sieve failed with unsuccessful implicit keep (user logfile /maildir/e/example/.dovecot.sieve.log may reveal additional details)
I expect that there would be quota calculation errors as dovecot could not reach the database server, but what worried me was the 'failed to store into mailbox' message from sieve. The 'Trash' mailbox in this particular seive script is the correct location for the message to be filed into, but the worrisome message is the 'failed with unsuccessful implicit keep'.
I looked through all the message-ids that reported this error and I found that the messages were properly delivered in the end, so this might be some issue interacting between sieve, dovecot and quota and just causing a scary message that can be ignored?
thanks for any information you can provide, dovecot is great!
