Hi,

I am getting the error "Error: Mailbox Spam: Failed to autocreate mailbox: Mailbox can't be created" and cannot figure out what is causing it.  It seems like some sort of permissions issue, but nothing I have tried seems to fix the problem. I was running my setup for many years without issue, and this error started occurring after a recent Ubuntu upgrade.

I am using getmail 6.18.4 to fetch mail from a mail server, which then calls /usr/lib/dovecot/deliver to deliver the mail to my local system. It is during this delivery that the error occurs. The dovecot-lda executable exits with status 75 and the log file contains:

Jun 09 08:05:54 honeydukes dovecot[1863]: lda(sally)<1863><L9pgDaKaZWZHBwAASkLcPA>: Error: Mailbox Spam: Failed to autocreate mailbox: Mailbox can't be created Jun 09 08:05:54 honeydukes dovecot[1863]: lda(sally)<1863><L9pgDaKaZWZHBwAASkLcPA>: msgid=<REDACTED>: save failed to open mailbox Spam: Mailbox

Below is my dovecot configuration.

Any help would be appreciated!
