I to am having the same problem.    I have a user called at  and when I do a cyradm lm command it is listed.
In my imapd.conf file, I have specified the following parameters:
unixhierarchysep:      yes
virtdomains:              yes

I have also modifed my so the cyrusv2 listing has the following parameters:

When I send an email to that user, it gets through Sendmail okay, who sends it on to cyrusv2 - who rejects it for the same errors as below.

Does anyone have any suggestions to what I've forgotten to do, that would be causing this problem?  Also does anyone know what the proper way is to specify the cyrusv2 options in is?

Thanks for any assistance!

Subject: Virtual domains, user at Mailbox unknown

Hi all,


I have a problem, I use multiple domains but for users I create with the
domain specified, for example postmaster at it can't receive
mail. When I try to send to this user I get back a reply from Mailer-Daemon
that says "550-Mailbox Unknown". Either there is no mailbox associated
550-name or you don't have authorization to see it".


If I create the user "user.postmaster" it works fine, but the user
"user.postmaster at" wont accept any mail.


Here is my imapd.conf:


configdirectory: /var/imap

partition-default: /var/spool/imap

admins: cyrus root Henrik

sasl_pwcheck_method: saslauthd

sasl_mech_list: PLAIN LOGIN

sendmail: /usr/sbin/sendmail


virtdomains: yes



I have set up the domain in the local-host-names config file for sendmail. 


Here is the error message:
