Myabe a new featire request too (and maybe in plugin).

• In OptOut system:
  Add 2 checkbox:
• one checked: remove my email adress for this survey
• one unchecked: remove my email adress for all email adress on this system

BLacklisting blacklists the user, not only the email. If you add the user from CPDB to the tokens it should blacklist it properly. Otherwise CPDB does not know about it.

Yes,

But need too blaclisting email, not only user, no ?
And need a plugin for this ?

For user: it's more inscription , not blacklisting.

A lot of "mail sending" system have a global blacklist, and think it's needed by some law in some country.

Yes, I am not saying it is perfect, just that it is not a bug. :-)

OK,

Then allowed to

• Test if email is not in blacklist when sending invitation/remind
• Test if emil is not in blaclist with all other email (not sure for this one)
• Add a globalsettings to deactivate this system (maybe 0: deactivate, 1 : public system (invitation/remind/inscription), 2: all). Default to 1
  For 2.0 or 2.05 ?

Start a plugin to set this globalsettings in globalsettings (2.05?2.06?)

Both 2.05 at earliest

We don't have a feature request about this ?
