We've recently made the switch from sendmail to postfix at my place of
employment, and we're lovin' it so far :).

We have run into a minor hangup -- we have a large popular of users here
who are used to sending email to unqualified addresses (e.g., userfoo
rather than userfoo.company.com, where foo.company.com is a subdomain,
not a hostname).

I'm having some problems with the configuration on our perimiter mail
relay(s) -- they don't appear to be rewriting unqualified addresses as I
would expect.

I have the following in /etc/postfix/canonical:

  foo foo.company.com
  bar bar.company.com
  otherplace otherplace.company.com

The following in /etc/postfix/relay_domains:

  foo.company.com smtp:[mail.foo.company.com]
  .foo.company.com smtp:[mail.foo.company.com]
  bar.company.com smtp:[mail.bar.company.com]
  .bar.company.com smtp:[mail.bar.company.com]

And the folowing in main.cf:

  mydomain = foo.company.com
  mydestination = $myhostname, localhost.$mydomain,
      hash:$config_directory/relay_domains
  canonical_maps = hash:$config_directory/canonical

  transport_maps = hash:$config_directory/transport,
      hash:$config_directory/relay_domains
  relay_domains = $mydestination, hash:$config_directory/relay_domains
  masquerade_domains = hash:$config_directory/relay_domain

Both foo.company.com and bar.company.com are included in relay_domains and
in masquerade_domains.

Given the following session:

  HELO host.foo.company.com
  MAIL FROM: <larsfoo.company.com>
  RCPT TO: <larsotherplace>
  DATA
  ...
  .

I get errors because postfix rewrites <larsotherplace> to
<larsotherplace.foo.company.com> -- apparently ignoring the entries in
canonical_maps.

I'm assuming the problem here is actually my understanding of the whole
process, so I'd appreciate some pointers. Let me know if I've provided
insufficient information.

Thanks,

-- Lars
