Re: virtual user list in a passwd file (without linux user)
Thanks again for your help. It is really appreciated. Thanks for the reminder, I did implement the SPF part already. So, I got it to work by following your suggestion (2). I also changed a few things based on warnings I got in the logs and after more reading: ~~~ /etc/aliases postmaster: root nobody: root "root@localhost": root # redirect all root mails to this: root: postmas...@site1.com /etc/postfix/main.cf # changed the following myhostname = mail.site1.com mydomain = site1.com myorigin = $mydomain # removed all domains that were already in virtual_mailbox_domains mydestination = localhost.$mydomain, localhost virtual_mailbox_domains = site1.com, site2.com, site3.com, mail.site1.com, mail.site3.com, mail.site2.com ~~~ Well it is only off-topic when your are an expert at both. In my case, I am not always sure if I have to change something in dovecot or postfix since they work together in my setup.

Not sure what is the easiest way of doing this. Yes, if you only use 'postmaster' in virtual it will expand to this address as you have 'mydomain = mail.site1.com', and so Dovecot cannot find it. I'd suggest the following, based on your current config: (1) Extend your main.cf -> virtual_alias_maps this way: virtual_alias_maps = hash:/etc/postfix/virtual, pcre:/etc/postfix/virtual_rfc (BTW, I suggest to use 'hash' instead of 'texthash' you used as with the former Postfix is able to automatically detect changes of these maps and a 'Postfix reload' isn't necessary.) In virtual_rfc something like this: /^postmaster@/ postmas...@site1.com /^abuse@/ postmas...@site1.com /^hostmaster@/ postmas...@site1.com /^webmaster@/ postmas...@site1.com (Hint: in contrast to hashed tables (see above) pcre lookup tables are simple text files, so you have to do a 'Postfix reload' after changing them.) or (2) Alternatively and instead of such a pcre map you could still use: virtual_alias_maps = hash:/etc/postfix/virtual and put all these aliases in the virtual file: ab...@site1.com postmas...@site1.com ab...@site2.com postmas...@site1.com postmas...@site2.compostmas...@site1.com ab...@site3.com postmas...@site1.com postmas...@site3.compostmas...@site1.com ab...@site4.com postmas...@site1.com postmas...@site4.compostmas...@site1.com [...] --> after editing of course a 'postmap /etc/postfix/virtual' It depends on the number of domains which option is less expensive. As this all is mostly MTA/Postfix related and so quite off-topic here maybe it's better to switch to direkt e-mail if we have to look at it further?

Re: virtual user list in a passwd file (without linux user)
Sorry for the delay but after debugging, I realized that Azure was blocking
outgoing port 25 on my VM. I had to move my mail server to another hosting
server which involved using Apache reverse proxy with mod_md to get the
certificates on the new standalone mail server. So, this part works now, and I
reverted to trying to make dovecot/postfix work.
I may have to go on therapy after all this, it is draining my morale

Thanks for helping!
Good find, for sure the ':' was missing.
I am surprised dovecot did not complain about the user names with a {plain} in
them or that users did not have a password defined in the password file.
Now the query with doveadm works if I specify us...@site1.com.

virtual user list in a passwd file (without linux user)
Hi,
I am trying to have a virtual user list in a passwd file (without linux user)
but it does not seem to work.
I have been trying to make this work for days reading the dovecot documentation
and whatever I could find online...
Note that I did not enable imap since I only use pop3s to retrieve my emails.
I also tried to follow this guide:
https://doc.dovecot.org/configuration_manual/howto/simple_virtual_install/
Note that once this works for dovecot, I plan to have postfix use the dovecot
auth service to authenticate the virtual users and validate mail boxes.
# cat /proc/version

I tried using doveadm:
# doveadm user user1
userdb lookup: user user1 doesn't exist
field value
# doveadm user us...@site1.com
userdb lookup: user us...@site1.com doesn't exist
field value
I also tried with the verbose on (removed all the 'usually intentional'):
# doveadm -Dv user us...@site1.com

I could not find a way to list either the mailboxes or virtual user list that
dovecot is using/serving.
