There is a -m option in the lda delivery where you can give namespace prefix. Maybe it's good for this, but I couldn't find any information how can I do this with lmtp?
If you set:
lmtp_save_to_detail_mailbox = yes recipient_delimiter = #
you could alias info@domain.com to
What kind of alias do you think? At smtp time, like in the /etc/aliases? Eventually, i can configure exim to accept the "#" and "/" chars in the email address.
<user>#Public.Mailbox.Folder@domain.com . 1st option tells LMTP to use the detail (subaddress) as default mailbox, which is essentially the same as the -m option of the LDA. 2nd options sets the delimiter of user and detail. <user> must habe write permission to the folder.
