dovecot - Aug 2011 - lmtp bouncing -- Invalid parameters (in reply to MAIL FROM command)

I just configured postfix' virtual_transport to point at my dovecot
director, but am seeing occational problems like this:

	Aug 31 11:50:06 smtpgw postfix/lmtp[5339]: 69E2F5410D: to=<email at
example.net>, relay=loadbalancers.example.net[192.168.42.17]:24, delay=0.15,
delays=0.14/0.01/0/0, dsn=5.5.4, status=bounced (host
loadbalancers.example.net[192.168.42.17] said: 501 5.5.4 Invalid parameters (in
reply to MAIL FROM command))

but can't find anything interesting in the dovecot logs.. Anybody have 
ideas for how to make postfix play nice with dovecot's lmtp ?

	smtpgws% rpm -q postfix
	postfix-2.3.3-2.1.el5_2

	loadbalancers% rpm -q dovecot
	dovecot-2.0.13-2

	backendmailstorers% rpm -q dovecot
	dovecot-2.0.13-2

Further digging shows that these messages are from an address containing
quotes and spaces:

	mail from:<"a b"@no.no>
	501 5.5.4 Invalid parameters

Testing with postfix + dovecot lda (v1.2.16) the messages gets
trough just fine. Is this auth_username_chars kicking in, or some
other check of valid characters in lmtp from ?

This is fixed in v2.0.14.
