Hi all,
I'm having a difficult time understanding why one of my machines is
showing modified "Return-Path" and "From" headers while another is not.
I'm hoping someone can point me in the right direction. Here's the
environment:
Two CentOS 4 servers, both running the same version of Postfix (2.2.10).
This was installed via binary RPM so I'm certain the Postfix build is
identical.
My issue is this: When mail is sent to one of the servers ('cam-d3'),
the "From" header is modified to have "owner-" prefixing the actual
address from which it was sent. Similarly, "Return-Path" is updated to
include an "owner-" prefix. This is not happening on the other server
('imps') and I have no idea why.
I don't know what information would be relevant here so here are some
selected data points (taken from root's 'mbox' and live configuration
data). First, I've attached an example of a message sent to an address
on the machine which adds "owner-". Here are abbreviated headers
showing the "From" and "Return-Path" changes:

The address is an alias to root and the "owner-" prefix is added
regardless of source address.
Contrast this with a message sent to an address on the other machine:

I'm quite confused by this. The "owner-" prefix is similar to a VERP
address, but I can't find any VERP-related configuration settings
enabled on either server.
I also dumped the full configs on both servers via 'postconf' and
diff'ed them. There are three differences:
1. alias_maps on the server adding "owner-" contains an additional
MySQL-based alias_maps entry, but since I'm using a hash-based entry for
my test this should not be hit. (Testing confirms this.)
-alias_maps = hash:/etc/postfix/maps/hash/aliases
+alias_maps = hash:/etc/postfix/maps/hash/aliases,
mysql:/etc/postfix/maps/mysql/mysql-alias-maps.cf
2. local_recipient_maps is using a hash instead of a MySQL for
local_recipient_maps. (MySQL isn't installed on one of the hosts.) The
content is identical between the hash file and the MySQL table.
-local_recipient_maps = proxy:unix:passwd.byname
hash:/etc/postfix/maps/hash/local-recipient-maps
+local_recipient_maps = proxy:unix:passwd.byname
mysql:/etc/postfix/maps/mysql/mysql-local-recipient-maps.cf
3. 'mydomain', 'myhostname', and 'mynetworks' differ since the servers
are listening serving different domains, have different hostnames, and
are on different networks. These all match the OS-level configuration
data.
Any guidance would be much-appreciated.
Regards,
Damon
