dovecot - May 2008 - dovecot + exim + verify recipient / reject bad recipient at SMTP time

hello,

I'm quite new to dovecot. My instalation is working good
Debian Etch
	- exim: 	4.63-17
	- dovecot:	1.0.rc15

I'm using virtual user setup, with LDA delivery method. There is no database
backend at this
time.

Is there any way to configure exim to reject non-existing user /asking dovecot
lda/
at SMTP time. The standard exim configuration in ACL section do not work:
--- cut ---
   require message   = e-mail address is not valid ($local_part@$domain /
$recipient_verify_failure)
     domains   =  +virtual_domains
     verify    = recipient
--- cut ---

Please, have any work working example ? This setup work good witch cyrus-imap
and LMTP.

	best regards
		Peter Hudec

No, unless you make the SMTP session wait until mail is delivered. And I
don't know if that's possible.

There is some semi-standard protocol to ask if a user exists. Dovecot
should probably support it some day.
