But in this case, I think it is the only way for me to illustrate my
frustration with this problem. Why is there no lookup of
virtual_mailbox_maps to notice that the recipient is to be routed to
a virtual mailbox.
Postfix behaves as documented. For an address to be delivered to a
virtual mailbox, the domain must be listed in
virtual_mailbox_domains, and the user must be listed in
virtual_mailbox_maps.
Verbose logging is unlikely to help.
Things that might help are:
- use postmap -q to test your lookup tables.
- use postconf to verify your main.cf settings.
- relevant docs:
http://www.postfix.org/postconf.5.html#virtual_mailbox_domains
http://www.postfix.org/ADDRESS_CLASS_README.html
http://www.postfix.org/VIRTUAL_README.html#virtual_mailbox
http://www.postfix.org/DEBUG_README.html
If you have a small number of virtual domains, specify the domains
directly in main.cf:
# main.cf
virtual_mailbox_domains = example.com example.net
Otherwise, provide a dedicated virtual_mailbox_domains map.
Of course I can provide a dedicated virtual_mailbox_domains map - that
is what I do in my working configuration at the moment. The reason for
trying to avoid it is preparation for moving to SQL and wondering if I
could avoid the extra query.
I have read all the docs referenced above several times, and what it
says in there is that if I don't mention virtual_mailbox_domains it
defaults to
$virtual_mailbox_maps - as mentioned here for instance
http://www.postfix.org/postconf.5.html#virtual_mailbox_domains
But to be absolutely clear about it, as you can see above from my
postconf -n output, I explicitly make that reference. But even so,
Postfix does not appear to be using this map.
So the reason I turned on verbose logging was to see what Postfix was
actually doing - but it never even mentions it in the log. So as you
say, turning on logging, in the end appeared unhelpful.
What I am becoming to realise - but which I can't find documented
anywhere is that there is a subtle difference between a map of domains
(as keys) and a map of e-mail addresses (as keys), and although the
documentation tells you that virtual_mailbox_domains defaults to
virtual_mailbox_maps, it actually can't because the former is a list of
domains and the latter is a list of e-mail addresses, and it cannot
extract the domains from the e-mail addresses.
