Hi Jaroslaw,
Thank you for your suggestion.
I've indeed explored the option of adjusting the limits in the code, and I've
been maintaining a patched version for my specific needs for quite some time
now. However, I've also encountered others who faced similar challenges and
found the patched v
1) You can log full headers with a Milter. You will run into the
length limit of the syslog() client (historically, 2 kBytes) before
the Milter protocol limit (64 kBytes) which is less than the Postfix
header_size_limit (default: 102400).
2) You can uniqely identify all Postfix transactions with a

Initially, I experimented with a Milter for logging the required headers, but I
found that employing a larger %s printf value proved to be a more efficient
solution. However, I'd like to point out that the default configuration for
MaxMessageSize in rsyslog is often set to 8k, with the potential

Oops! I just realized that I sent this instead of saving it. Dang!
So continuing my thoughts with item 4 ...
4) Probably not a PostFix question, but it is related. One big reason
for doing an in-place upgrade is because I do not know how to move my
mailbox from the old server to something n

Hi Victor,
Thank you for diving into this topic.
Using a Milter is an option, but it often involves correlating information from
both the milter process and the log for a comprehensive view. For example,
capturing TLS details from both the smtp client process and smtpd pid, along
with recipien

Hi Gerald,
Thank you for providing an insightful perspective on the matter, and you've hit
the nail on the head. Indeed, the 200-byte limit not only impacts the display
of subjects but also affects headers with security content, such as
Authentication-Results. A Milter cannot get any informatio
