Why is nullmailer appending my hostname to the recipient address?












0















I want to set up nullmailer to relay mail to my provider's SMTP.



Since the provider drops email with mismatching sender's domain and user login, I used /etc/nullmailer/allmailfrom to match the login from /etc/nullmailer/remotes and it works, I can send email to fully qualified addresses.



I also used /etc/nullmailer/adminaddr to redirect all local emails [user]@localhost to default@myowndomain.net. This is because according to man nullmailer-queue




   adminaddr
If this file is not empty, all recipients to users at either
"localhost" (the literal string) or the canon‐
ical host name (from /etc/mailname ) are remapped to this
address. This is provided to allow local daemons
to be able to send email to "somebody@localhost" and have it go
somewhere sensible instead of being bounced
by your relay host. To send to multiple addresses, put them all
on one line separated by a comma.



Now I want to have myowndomain.net appended to generic usernames (mail any_username). According to man nullmailer-inject,




   defaultdomain
The content of this file is appended to any host name that
does not contain a period (except localhost),
including defaulthost and idhost. Defaults to the value of the
/etc/mailname system file, if it exists,
otherwise the literal name defauldomain.

defaulthost
The content of this file is appended to any address that is
missing a host name. Defaults to the value of
the /etc/mailname system file, if it exists, otherwise the
literal name defaulthost.



From what I understood, I should use /etc/nullmailer/defaulthost because I am sending emails to addresses missing a host name. Therefore I placed there myowndomain.net.



However, nullmailer still appends @hostname.myprovider.net, resulting in emails dropped by the SMTP relay host: said domain does not exist.



How can I configure nullmailer to just add @myprovider.net instead of @hostname.myprovider.net to addresses missing a hostname?
