I have written a router and transport with the keyword unseen
The source is;
relay_by_vps:
debug_print = "R: Relaying by vps for $domain"
driver = manualroute
domains = ! +local_domains
same_domain_copy_routing = yes
route_data = vps.lesve.org::587
transport = remote_smtp_smarthost
headers_remove = X-Interface: X-Remote: X-Helo
unseen
save_to_mailbox:
debug_print = "R: save_to_mailbox"
driver = manualroute
domains = ! +local_domains
transport = maildir_lesve
user = lesve
route_data = lesve
maildir_lesve:
debug_print = "T: maildir_home for user lesve"
driver = appendfile
directory = /home/lesve/Maildir/.Sent
create_directory
delivery_date_add
envelope_to_add
return_path_add
maildir_format
So to the problem:
The email is copied twice to the maildir But when a try to debug it with the -d it will work with one delivery to maildir
