The mailing list for listmasters using Sympa

[David Verdin <address@concealed>]

Hi,

Sympa doesn't have an option to add missing message-id.
I would rather see the MTA adding a missing message-id, because it 
handles all the incoming SMTP checks.
But I see a few problems related to it:

- can't adding the message-ID header break the signature of a signed 
message?
- if a client doesn't add the Message-ID, won't it also fail to add the 
"In-Reply-To", used to build threads?
- it could be possible with Sympa, because it could check if the 
messagef is signed first, or sign it itself, event if the original 
signature is broken. But again, I'm not sure it is the best option.

Regards,

David
