@Thomas: No, there is no way to change the subject or any other part of

emails in general) are not really designed for allowing such changes. 
For example, for IMAP it would require re-uploading the entire message 
to the server (also if it has a 20MB attachment). If I ever implemented 
anything to support such changes then I would probably do it by placing 
the changes in some kind of meta-message, but this would not work well 
with other email clients.



Could a redirect with the addition of additional info be a solution.


When I implement redirection then I don't think I would allow changing 
the content. The standard does not even support a change of the subject 
line: http://tools.ietf.org/html/rfc5322#section-3.6.6


I could perhaps allow a `Resent-Subject` (and/ore `Resent-Note`) header 
given that I warn the user that most email clients are unlikely to 
display this value. (This would still not be very efficient with regard 
to re-uploading to the server, but at least it would be an explicit 
change of the message.)


@ Benny: we have a similar situation and this is why i requested the 
possibility to be able to redirect a mail, I know your vision on 
changing mail contents and understand the risks/issues, but then again 
if other mail clients allow it . . .


If my general measure of correctness was other mail clients...

I'll give it some more thought.

[MlMt] Änderung des Betreff der eingegangenen Nachrichten

2013-12-12 Thread Thomas Wölk

Hello,

Is there a way to change the subject for already received messages? A 
customer wants to subsequently missing data (project number, transaction 
number, ...) to change the incoming e-mails, if this information had 
been forgotten by the sender. (MS Outlook allows this option.)


Background: Users often forget to write in the subject the project 
number or project number is incorrect.
