Hi Philipp You are completely right, the proposed solution doesn't work. It seems exim always qualifies an address without a domain, I believe this is because LMTP requiers to get only qualified addresses (LMTP is based on SMTP and the RFC, if I read it correctly specifies it like this).
So, another solution would be to use LDA for your local users and LMTP for the rest. The configuration for exim would be: a router and a transport for your local users using LDA, and your virtual users setup as you have it using LMTP. local_user: debug_print = "R: local_user for $local_part@$domain" driver = accept domains = @ : localhost : ${primary_hostname} check_local_user transport = dovecot_lda cannot_route_message = Unknown user dovecot_lda: driver = pipe command = /usr/lib/dovecot/dovecot-lda \ -f $sender_address \ -a $original_local_part@$original_domain log_output delivery_date_add return_path_add envelope_to_add user = $local_part group = mail temp_errors = 64 : 69 : 70 : 71 : 72 : 73 : 74 : 75 : 78 Please check man dovecot-lda and the dovecot wiki (http://wiki2.dovecot.org/LDA/Exim) for details. Also check the permissions you need for dovecot-lda to write to your mailspool (user and group options from the transport). I haven't tried the above, but I think it works like this ...
