Hi,
you read an article from thuban. Original link is there :
https://ybad.name/ah/fr/05-mail/ i suggest you to read the full article
with virtual users.
I suggest also to read the article from the creator of opensmtpd :
https://poolp.org/posts/2019-12-23/mettre-en-place-un-serveur-de-mail-avec-opensmtpd-dovecot-et-rspamd/
(french)
https://poolp.org/posts/2019-09-14/setting-up-a-mail-server-with-opensmtpd-dovecot-and-rspamd/
(english)
From my understanding you need just to manage your system account as a
simple Maildir Mailbox on a system user or a virtual user.
In this way : edit /etc/mail/aliases and to route all account like root,
postmaster, www --> to the user system
example :
(...)
# Well-known aliases -- these should be filled in!
root: <local account>
# manager:
# dumper:
<local account>: <virtual email or local email>
(...)
All system account will be routed to root... and root will be routed to
<as you want> ... Mail to original target will not be deleted, simply
routed.

Hi,
I am new to mail servers, and I ran into a nice tutorial from a French
NGO. However, I'd like to tweak a bit my configuration, and I cannot
find a proper way to achieve my goal: I want to discard mails whose
recipient is the address my_system_u...@my-domain.net
<mailto:my_system_u...@my-domain.net> (and r...@my-domain.net
<mailto:r...@my-domain.net> and so on), while accepting mails to be
routed to my_system_user, through a list of aliases or virtual users.
In fact, I want all the mails to go through this system user, and to
be read by a unique dovecot account (hence, I'd say the simplest way
to do is to have an unique Maildir?).
I created a thread on Stack Overflow for that matter:
https://stackoverflow.com/questions/64715521/prevent-mailing-to-my-username-in-opensmtp-config
<https://stackoverflow.com/questions/64715521/prevent-mailing-to-my-username-in-opensmtp-config>
; its content is below:
I just set up my own mail server at home with OpenSMTP and Dovecot
(I used this tutorial
<https://framacloud.org/fr/auto-hebergement/installation.html#courrier-%C3%A9lectronique>
from Framasoft). I don't like the idea that people can mail to
/my_system_u...@my-domain.net
<mailto:my_system_u...@my-domain.net>/ or /r...@my-domain.net
<mailto:r...@my-domain.net>/ (or any other system user), although
I'll use this only /my_system_user/ account to receive my mails.
That's why I added |root: /dev/null| and
|my_system_u...@my-domain.net
<mailto:my_system_u...@my-domain.net>: /dev/null| to my
|/home/my_system_user/.myaliases| file (+ |makemap -t aliases
~/.myaliases|). But I still receive the mails for
/my_system_u...@my-domain.net
<mailto:my_system_u...@my-domain.net>/. Maybe I shouldn't go
through the hassle of preventing this?

In my search, I found out that virtual users could be a solution
(source)
<http://z5t1.com:8080/cucumber/cucumber-1.1/source/net-extra/opensmtpd/doc/example1.html#stats>,
but it seems overkill to me (setting up a new /vmail/ user, new
password table, new services...): I have only one repicient
account with multiple (~10) aliases.
Any help is appreciated!
Best regards,
choumat
