Hi.
When relaying to an external service, I set a specific token in the mail header
to pass authentication.
I am able to send mails by adding the smtp_header_checks option to smtp in the
master.cf file.
However, it appears in /var/log/maillog.
Is there any way to avoid this?
[root@xxx-mail01
Note: OpenDKIM does not require the (ancient, obsolete) setting
‘milter_protocol = 2’. It’s a cargo cult setting. Just drop it and leave
it at the default.

Hi all,
I want to manipulate the headers (add and replace) of the outgoing mail
before the message is signed by Opendkim. If using smtp_header_checks I see
that the signature is broken - probably because Opendkim has signed the
message earlier in the pipeline.
The signing is configured via the
Many thanks for the reply.
In fact I found a small workaround, which of course adds more text to the
log file. But it serves the purpose.

Hi
I have setup smtp_header_checks to log subject lines in my mail log.
However the issue is messages are truncated to about 50 characters.
Is there any method to get the full Subject into log?

Many thanks and Best Regards

Thank you Viktor and Wietse for the help.
I decided to go through the milter approach.
Cheers,

Hey list,
I created the following smtp_header_checks rule:
smtp_header_checks = pcre:/etc/postfix/maps/header_checks
and /etc/postfix/maps/header_checks:
/^In-Reply-To:/ INFO
/^References:/ INFO
As I aim to have such header logged on syslog.
The issue I'm facing is that all mes

Hello Wietse & Friends,
/etc/postfix/main.cf looks like this:
header_checks = regexp:/etc/postfix/header_checks
smtp_header_checks = regexp:/etc/postfix/header_checks
/etc/postfix/header_checks looks like this:
/^Subject:/ WARN
Two issues:
1. I have a really long subject.

Or would you suggest writing a custom smtp milter to do the same job
Milters run on input.
You should be able to use Sahil's tcp header checks service
with smtp_header_che

Postfix truncates EVERYTHING, especially when it is
I am using postfix smtp_header_checks to log subjects of mails
I have enabled WARN inside smtp_header_checks
But If I send a mail with a long subject then the subject gets chopped
at some length (approx 50 chars )
Is this documented somewhere (max length of WARN). ?

Any idea of how to do this?
According to:
http://www.postfix.org/header_checks.5.html
there is definitely a DISCARD action.
And, it's header_checks, not smtp_header_checks:
