Hostname in OX Message-ID Header-Field

[Gobitodic]

Hi,

i'm using Open-Xchange 6.22.3 in combination with iRedMail and fetchmail under Debian Squeeze. All basic funtions are working quite well.

I use my ISP's SMTP-Server as relayhost, which is also working. Now I want to hide information about local hostnames in the mail headers. I managed to adjust the configuration files of postfix/amavis etc. but I don't know how to get rid of the following infomation in my outgoing mails:

Message-ID: <1234567890.1.1234567890.open-xchange@[local-hostname].[local-domainname].local>

In which configuration do I have to change settings to change the line to

Message-ID: <1234567890.1.1234567890.open-xchange@[public-domainname].[tld]>

Has anybody an idea how to manage this.

Thanks a lot

Gobi

Hi,

as I did not find the corresponding configuration file in open-xchange I solved my problem by using the header_checks-function in postfix.

/etc/postfix/main.cf

header_checks = regexp:/etc/postfix/header_checks

/etc/postfix/header_checks

/^Message-ID:.*[local-hostname].*/ IGNORE
