Hello,

I found a small bug in the online documentation on this page:

http://www.postfix.org/postconf.5.html

The option "message_size_limit" is described as:

"The maximal size in bytes of a message[..]",

The documentation is correct.

As the documentation says "maximal size in bytes of a message,
including envelope information". The limit also includes headers
that Postfix adds to the message such as Date:, From: and Received:.

Well, I have here an setup with message_size_limit being 21000000, which, by your math would calculate to: 21000000 bytes = 20507.8125 KiB = 20.027160645 MiB.

According to my math, where 8 bit equals 1 byte:

21000000 bit = 2625000 byte = 2563.4765625 KiB = 2.503395081 MiB

We clearly have set up a maximum message size limit of the latter (2.5 MiB). I don't get mail out of this system bigger than that.

Maybe I don't get it, or you use different representations of what is an byte or KB instead of KiB? If I'm seeing something wrong please point me to my failure. :-)

I noticed the part about the header, but we're talking about a difference of ~17 MiB. This large amount can't just be headers, can it?

Kind Regards

Sven
