I now have this working properly for a test account. It seems to me
now that many of my difficulties stem from trying to map Sendmail
techniques to Postfix.
I am now considering the relationship between /etc/postfix/virtual and
/etc/postfix/relay_domains. To deliver email to a local mailbox where
the mailbox_transport has been defined, as is the case when delivering
to cyrus-imapd users, the address must be defined in either the
local_recipients_maps or the virtual_aliases_maps. Further, it seems
that domains other than the host's domain must be specified in both
virtual_alias_domains and relay_domains.
>From my readings of the various bits of documentation it appears that
the virtual domains and the virtual aliases may reside in the same
map.
Thus this is possible in /etc/postfix/virtual:
# These are the virtual domains
example.com -
.example.com -
# These are the virtual aliases
firstu...@example.com firstuser
@example.com mailbag
However, for Postfix to accept the mail for a virtual domain int he
first place it seems to me that domain must be given to the
relay_domain variable. The form as I understand it is:
#/etc/postfix/relay_domains
example.com -
.example.com -
My questions is: Why not simply map all three as shown below?
#/etc/postfix/main.cf
relay_domains = hash:/etc/postfix/virtual
virtual_domains = $relay_domains
virtual_aliases_map = regexp:/etc/postfix/virtual.regexp,
$virtual_domains
Is the separation of relay_domains and virtual_domains simply to allow
reception of domains that are then forwarded on by the transport map
instead of delivered locally? If so then the question still remains:
why the distinction between virtual_domains and virtual_aliases_map?
