I am new to Postfix and I am having trouble getting a feature that I
have working on our existing Sendmail delivery system to function on
the new Postfix delivery system.
Basically, I want all incoming email that does not have a + extension
such as localu...@example.com to deliver to
/var/spool/imap/l/user/localuser/delivery instead of just
/var/spool/imap/l/user/localuser.
On the other hand, anything that has a + address portion still gets
delivered directly to that subtree. For example
localuser+contract.q201...@example.com delivers to
/var/spool/imap/l/user/localuser/contract/q201110.
This works for our local and our virtual domains. Since the number of
actual users is quite small we use local system accounts (passwd) for
authentication.
The cyrus-imap configuration files cyrus.conf and imapd.conf on the
new Postfix server are in all respects identical to those on the
present Sendmail delivery server.
It took me a very long time to get this to work in Sendmail and it is
so long ago that I cannot remember much of the process. However, our
existing Sendmail virtusertable looks like this:
localu...@example.com localuser.delivery
realname.localu...@example.com localu...@example.com
deepn...@example.com deepuser.contract.other
On the Postfix system the virtual domain example.com is listed in the
virtual_domains file and the map is built with postmap.
example.com -
.example.com -
I have experimented with regexp mappings for virtual aliases but these
have all been removed. For the moment we are just using the virtual
alias map. The contents of /etc/postfix/virtual are:
tes...@example.com bylmbx003
tes...@example.com bylmbx003.delivery
tes...@example.com bylmbx003+delivery
The relevant settings in /etc/postfix/main.cf are:
soft_bounce = yes
mydestination = $myhostname, localhost.$mydomain,
hash:/etc/postfix/local_domains
unknown_local_recipient_reject_code = 550
alias_maps = hash:/etc/postfix/aliases.main
alias_database = hash:/etc/postfix/aliases.main
recipient_delimiter = +
mailbox_transport = lmtp:unix:/var/lib/imap/socket/lmtp
transport_maps = hash:/etc/postfix/transport
virtual_alias_domains = hash:/etc/postfix/virtual_domains
virtual_alias_maps= regexp:/etc/postfix/virtual_aliases_regexp,
hash:/etc/postfix/virtual
The results of sendmail -bv are:
***********
test1@
This is the mail system at host inet17.hamilton.harte-lyne.ca.
Enclosed is the mail delivery report that you requested.
The mail system
<bylmbx...@inet17.hamilton.harte-lyne.ca> (expanded from <test1@xxx>):
delivery via
inet17.hamilton.harte-lyne.ca[/var/lib/imap/socket/lmtp]: 250
2.1.5 ok

test2@
This is the mail system at host inet17.hamilton.harte-lyne.ca.
Enclosed is the mail delivery report that you requested.
The mail system

2.1.5 ok
However, the mail ends up in b/user/bylmbx003 and not
b/usr/bylmbx003/delivery

test3@
This is the mail system at host inet17.hamilton.harte-lyne.ca.
Enclosed is the mail delivery report that you requested.

<test3@xxx>): delivery via
inet17.hamilton.harte-lyne.ca[/var/lib/imap/socket/lmtp]: 250
2.1.5 ok
This also ends up in the imap INBOX and not in the subfolder.

This does not arrive in the delivery folder either
****************
Evidently, my first difficulty is getting Postfix and Cyrus-imap to
agree on the + delivery semantics. However, I have exhausted my own
resources in pursuit of a solution. As far as I can tell I have
configured Postfix to deliver extended addresses properly and I have
made no changes to the cyrus-imapd configuration as they exist on the
Sendmail server, where the extended mailbox addresses work as I
expect. In fact, these files were copied over from there and compared
to the clean distribution copies before replacing those.
If another pair of eyes sees anything I am doing that is wrong I would
appreciate being told what it is.
