Hi,
Sorry if I am not posting on the right mailing list, but I need email
and especially IMAP experts opinion.
I have developed a small perl script for Amavis that tries to recognise
business emails from bulk & mailing lists, in order to promote
'important' emails, ala google. This is a feature I found very useful in
corporate environments, where a lot of users are receiving
advertisements, but not consider it as spam. (For info, the code is
here: https://github.com/arodier/emclass)
My script add an email header (X-Email-Type), and dovecot uses a virtual
folder called 'Important' to present them.
I know there is IMAP labels, and they are server side stored. I have
successfully played with Thunderbird, but IMHO, it's not very reliable.
The name of the label is the responsibility of the email client. As a
result, if one client decided that $Label1 is 'Important', and $Label2
is 'Business', other clients should be configured exactly the same.
I wonder if there is some norm - or convention - to attach labels to
email headers, or if such a header exists, for instance a header called
e.g. 'X-Tags', 'X-Keywords' or 'X-Labels'.
So, once stored, an email could contains - for instance - a header like
this:
X-Tags: Travel,Advertisement,France.
Then, it would be easy to have server side search for labels.
Thanks for your feedback.
Kind regards,
Andr?.
