Update to dovecot-1.orc8.  From the release announcement mail:

I've still over 200 mails unread in the mailing list, and important
things left in TODO. This release is an improvement over rc7 anyway,
hopefully I'll have time to fix the rest soon.

	* GSSAPI: Changed POP3 service name to "pop", which is what the
	  standard says
	* "mbox:/var/mail/%u" no longer works as the mail location. You'll
	  have to specify the mail root explicitly, just like the examples
	  always have: "mbox:~/mail:INBOX=/var/mail/%u"

	+ SHA1, LDAP-MD5, PLAIN-MD5, PLAIN-MD4: The password can be now either
	  hex or base64 encoded. The encoding is detected automatically based
	  on the password string length.
	+ Allow running only Dovecot master and dovecot-auth processes with
	  protocols=none setting
	+ deliver: -f <envelope sender> parameter can be used to set mbox
	  From_-line's sender address
	+ deliver: Log all mail saves and failures
	+ Tru64 SIA passdb support. Patch by Simon L Jackson.
	- INBOX was listed twice in mailbox list if namespace prefix was used
	- INBOX-prefixed namespaces were a bit broken
	- kqueue: Fix 100% CPU usage
	- deliver: Duplicate storage was a bit broken
	- dictionary code was broken (ie. dict quota)
	- SIGHUP caused crashes sometimes
