I had recently upgraded from Dovecot 1.0.14 to 1.1.0, and then to
1.1.1. Ever since the upgrade to 1.1.0, I noticed that "plus
addressing" has failed. In case I'm using a foreign phrase, this is
the concept of sending an e-mail to "[EMAIL PROTECTED]", and having
dovecot (dovecot LDA, specifically), deliver this to the "spam"
submailbox to "[EMAIL PROTECTED]". I've been using this successfully
since 1.0.3.
When I upgraded to 1.1.0, I noticed that e-mails were no longer being
delivered to the submailboxes as they had been (though they would
arrive in the central INBOX). I checked the "dovecot-deliver.log", and
I noticed that, ever since I had brought up 1.1.0, I would see:
save failed to spam: Unknown namespace
("spam" is the submailbox)
After the upgrade to 1.1.1, I still would see these messages (and
behavior). I have since installed 1.0.15. The plus addressing now
works again, as it had been.
With all of these "upgrades" and "downgrades", the config file has
remained exactly the same. There have been no other changes to any
components on the host system (i.e., new OS-es, new postfix, etc.).
Thoughts? Is this a known issue?
