dovecot - Jun 2011 - Dovecot 2.0+LMTP: Legal MAIL FROM rejected?

Hi,

I run Dovecot 2.0.13 fed by Postfix over LMTP. Today it rejected one
mail Postfix and Amavis accepted, generating a bounce. It was just a
spammail, but I think the sender address is legal according to RFC5321
and should be accepted. I don't like generating bounces, email should be
either rejected by postfix/pre-queue-amavis or delivered.

Jun  6 12:32:47 mail postfix/qmgr[840]: 991FC240DB: from=<admin <admin at
kl38000.com>, size=8427, nrcpt=1 (queue active)
Jun  6 12:32:47 mail amavis[27046]: (27046-06) FWD via SMTP: <"admin

vmail.domain.com>, orig_to=<user at domain.com>,
relay=pop3.domain.com[::1]:24, delay=0.24, delays=0.09/0.11/0.03/0.01,
dsn=5.5.4, status=bounced (host pop3.domain.com[::1] said: 501 5.5.4 Invalid
parameters (in reply to MAIL FROM command))

It looks like dovecot/lmtp does not accept an address with quoted
localpart that contains a space

mail from:<"admin admin"@kl38000.com>
501 5.5.4 Invalid parameters
mail from:<"adminadmin"@kl38000.com>
250 2.1.0 OK
mail from:<"admin<admin"@kl38000.com>
250 2.1.0 OK
