Topic: X-Original-To:

I am looking for the configuration to add “X-Original-To:” in the head of the emails. I try to configure “enable_original_recipient = yes” in the main.cf, but it doesn’t help. What should I do?

I am working on Debian Squeeze with iRedMail 0.7.4 with MySQL Backend.

Thanks for help.

Re: X-Original-To:

I made it work with below settings.

1) Make sure you have below settings in Postfix main.cf:

enable_original_recipient = yes
dovecot_destination_recipient_limit = 1

2) Add flag 'O' (Letter o in upper case, not digit number zero) in Postfix master.cf for transport pipe:

dovecot unix    -       n       n       -       -      pipe
    flags=DRhuO user=[...OMIT OTHER SETTINGS HERE...]

3) Restarting Postfix service is required.

Re: X-Original-To:

Thanks for your help.

We need this feature for a multidrop configuration with one catch-all account. From the catch-all account we read all emails with fetchmail to our inhouse email server.

I try your configuration advice but unfortunately there is still a little problem. The “X-Original-To:” header is added but the address is wrong.

Example: 

iRedMail server domain: dcc-global.eu
catch-all account: www@dcc-global.eu
email recipient address: sven.just@dcc-global.eu

The following wrong header is added: 

X-Original-To: www@dcc-global.eu

the correct header would be: 

X-Original-To: sven.just@dcc-global.eu

I add the complete email header, I hope it helps you. If you need the complete configuration, please let me know.

Re: X-Original-To:

You can find several headers with value 'sven.just _at_ dcc-global.eu', are they enough for you?

Re: X-Original-To:

Unfortunately, not. We need the header to assign the e-mails with fetchmail the correct recipients.

Re: X-Original-To:

Thanks for your help, we solved the problem. Your post http://www.iredmail.org/forum/post14006.html#p14006 point us the right direction.

The problem was that mapping for the catch-all address was done by the postfix at port 25. At this time the envelope address is rewritten to the catch-all address. When the email comes to the postfix at port 10025 the envelope address is already the catchall address.

Therefore we need the first postfix at port 25 to not rewrite to the catchall address. With your hints and this idea in mind we do the following four adjustments:

1) Make sure you have below settings in Postfix main.cf:

enable_original_recipient = yes
dovecot_destination_recipient_limit = 1

2) Add flag 'O' (Letter o in upper case, not digit number zero) in Postfix master.cf for transport pipe:

dovecot unix    -       n       n       -       -      pipe
    flags=DRhuO user=[...OMIT OTHER SETTINGS HERE...]

3) In the Postfix master.cf we add the line (-o receive_override_options=no_address_mappings) after

smtp      inet  n       -       -       -       -       smtpd
   -o receive_override_options=no_address_mappings

4) In the Postfix master.cf we comment out one setting (#,no_address_mappings)

127.0.0.1:10025 inet n  -   -   -   -  smtpd
[...OMIT OTHER SETTINGS HERE...]
    -o receive_override_options=no_header_body_checks,no_unknown_recipient_checks
#,no_address_mappings

Now everything works fine. Thanks for you great work. smile
