I am trying to understand how my aliases/virtual_users/etc interact. postfix setup has virtual domains and virtual users, but all users (also those from different domains) are local dovecot IMAP mailboxes (“separate domains, unix system accounts”)
main.cf says it is the destination for: mydestination = $myhostname, localhost.$mydomain, localhost, $mydomain, $myorigin mydomain = rna.nl mydomain_fallback = localhost myhostname = mail.rna.nl mynetworks = 127.0.0.0/8, 192.168.2.0/24, [::1]/128 myorigin = dumbledore.rna.nl Aliases maps are defined in main.cf as follows: alias_maps = hash:/Library/Server/Mail/Config/postfix/aliases hash:/Library/Server/Mail/Data/listserver/aliases/list_server_aliases virtual_alias_maps = $virtual_maps hash:/Library/Server/Mail/Config/postfix/virtual_users hash:/Library/Server/Mail/Config/postfix/rna_virtual_users hash:/Library/Server/Mail/Data/listserver/aliases/list_server_virtual My /Library/Server/Mail/Config/postfix/aliases file contains: # Person who should get root's mail. Don't receive mail as root! root: gerben # Basic system aliases -- these MUST be present MAILER-DAEMON: postmaster postmaster: root postfix: root gerben is an existing local user with a dovecot IMAP mailbox who can receive mail. The result of trying to mail to r...@rna.nl or r...@dumbledore.rna.nl using SMTP from another system was originally: The server response was: <r...@dumbledore.rna.nl>: Recipient address rejected: User unknown in local recipient table The server’s name internally is dumbledore.rna.nl (presents itself as mail.rna.nl on the outside) and the same happened with the r...@rna.nl address or with ger...@dumbledore.rna.nl, but ger...@rna.nl worked. And postmas...@rna.nl worked and delivered to gerben’s dovecot mailbox. Why doesn’t this work? E.g. the server is the final destination for $myorigin which is dumbledore.rna.nl, but ger...@dumbledore.rna.nl doesn’t work. With the following in virtual_users: r...@rna.nl r...@rna.nl I can receive mail for root from another system via SMTP to r...@rna.nl, but I still cannot receive local mail to root from the local /usr/bin/mail or crontab to ‘root'. It seems that I must have a ~root/.forward with in it: ger...@rna.nl or I have to put the following in another /etc/aliases file (not the one postfix uses): root: ger...@rna.nl And not ‘gerben’ as otherwise, the mail ends up in /var/mail/gerben instead of in dovecot And I must enter the r...@dumbledore.rna.nl in my virtual_users as well: r...@rna.nl r...@rna.nl r...@dumbledore.rna.nl r...@rna.nl to have it covered, I have it working but it seems all a little complex to me and I get the feeling that I have made things overly complex. Am I correct? And what is preferred? An /etc/aliases file that is in use (next to the one I am using) or a ~root/.forward file?
