transport_maps missing in VIRTUAL_README for mail servers that relay for non-existing users
GK
I think: http://www.postfix.org/VIRTUAL_README.html
Might be missing a statement about transport_maps where there is
commonly an entry in setups requiring a forward to an ISP's smtp
server like:
$ cat transport
* smtp:[smtp.myisp.com]:587
Or similar catch-all line. The trivial-rewrite engine will promote a
virtual mailbox destination to use smtp transport in this case,
overriding previous successful lookups in virtual_mailbox_domains and
virtual_mailbox_maps.
E.g.
virtual_mailbox_base = /var/mail/box
virtual_mailbox_domains = ldap:.../postfix/root/conf/ldap-virtual-
mailbox-domains.cf
virtual_mailbox_maps = ldap:.../postfix/root/conf/ldap-virtual-mailbox-
maps.cf
transport_maps = hash:.../postfix/root/conf/transport
Send an email to some...@somedomain.com where both are looked up in
ldap-virtual-mailbox tables and at the end of processing the rewrite,
the log says:

This could be resolved by entering all virtual_domains manually into
the transport file with a virtual: column, but I think I'll try
prefixing the hash:transport lookup with a virtual_mailbox domain
search that returns virtual: for all found domains.
Thanks,
