First up, please see the output from "postconf -n" appended below.
I have just had to quickly rebuild a failed server and get it back into production. I have got basic functionality up and running but I've had to reconstruct the configuration as backups were incomplete (yeah I know!) It is now mostly working but there are some problems with my virtual domain config. For example: I am hosting the domains alpha.co.zz & bravo.co.zz on myhost.sierra.co.zz (not the real names) I have the following email accounts: al...@alpha.co.zz b...@bravo.co.zz s...@sierra.co.zz I also have a Mailman mailing list - "myl...@mailman.co.zz" I have Mailman setup to create /var/lib/mailman/data/virtual-mailman which is included in virtual_alias_maps There are various Unix user accounts on the server also. It is supposed to be configured as per "Non-Postfix mailbox store: separate domains, non-UNIX accounts" from the VIRTUAL_README documentation but I had some issues with Mailman integration which I think resulted from virtual_mailbox_maps so it is not precisely as described. In my /etc/postfix/virtual file I have: s...@sierra.co.zz sam al...@alpha.co.zz alice b...@bravo.co.zz robert Local email delivery is handled by LMTP via Cyrus-Imapd using mailbox_transport and virtual_transport. Email to b...@bravo.co.zz is delivered to the "robert" mailbox in /var/spool/imap/b/user/robert Email to s...@sierra.co.zz is delivered to the "sam" mailbox in /var/spool/imap/s/user/sam etc. The problem is that email addressed to s...@alpha.co.zz is also delivered to Sam's mailbox. Similarly al...@bravo.co.zz is delivered to Alice's mailbox regardless of the domain part. The Mailman config is working OK in that I can create new mailing lists, add subscribers etc. and mail sent to the address gets processed correctly. However mail sent to myl...@sierra.co.zz is also processed by Mailman. Currently there are no collisions in the name part of the email address but this is obviously not what I ultimately want. I've put this configuration together in a bit of a rush and the server is currently processing mail. There are no obvious error messages in the log. I'm sure that in the stress of getting things back online I'm missing something simple, possibly related to virtual_mailbox_maps, but I'm not sure what to set here so that Mailman updates things automatically. Could you please take a look at my settings and suggest where to look. Thanks in advance.
