Subject: DKIM on messages
From: scott@exussum.co.uk

Hi all,

Minor issue really but a fair chunk of the emails I get from the 
internals list end up in spam due to what looks like the DKIM signatures 
being incorrect.

If a message is DKIM signed, the signed part usually contains subject 
and body, this is then hashed and appended to the headers, after its 
been sent to the mailing list (where the signature is correct) the 
mailing list then prepends [PHP-DEV] to the subject and sometimes (not 
sure when but its not every request) puts an unsubscribe link in the 
body. As the message content has now changed, the signature also fails 
to verify.

It looks like ezmlm is used, there is an option for headerremove which 
DKIM-Signature could be added to 
(https://manpages.debian.org/experimental/ezmlm-idx/ezmlm-send.1.en.html) 
  this would prevent the signature being attached and therefore pass.

I imagine this is a fairly small issue, but it seems an easy fix also 
for someone with access to the mailing list.

Would it be possible for this to be applied ? as mentioned earlier this 
isnt major but I can't imagine I am the only one who has failures 
because of this.


Thanks

Scott
