No, it doesn't make sense. Either you allow your users to add 
addresses to the lists or you don't. There is a big message when users 
add an address, including a link to edit the list.

May I make this an enhancement request?

It has shown at our site that placing the "blacklist" in IMP on top of 
every page leads to accidental adding of addresses to the blacklist 
(and later discarded e-mails).
On the other hand this blacklist feature, accessible in Ingo, is useful.

It's not possible.

To make it clear:
  - I want let Ingo set the blacklist.
  - I don't want let Imp set the blacklist.
How to do that?

Thanks,
Frank

No, this doesn't make sense. We really want to check which app of the 
registry allows to *set* the list. Not which one allows to read it. 
What you want can't be done, because either you allow Ingo to set the 
lists, or you don't.

Hi,
I'd like to do the following
  1. disable the blacklist/whitelist "buttons" in mail index and mail view
  2. keep  blacklist/whitelist enabled in ingo

In horde/config/registry.php I removed 'mail/blacklistFrom', 
'mail/whitelistFrom'
from provides for ingo. Result:
  1. ok
  2. blacklist/whitelist butons in ingo are visable, but not the function -
     "Blacklist is not supported in the current filtering driver."

Proposed fix in ingo/lib/Script.php:

-        if ($key !== false && 
($registry->hasMethod('mail/blacklistFrom') != 'ingo')) {
             unset($this->_categories[$key]);
         }

         /* Determine if ingo should handle the whitelist. */
         $key = array_search(INGO_STORAGE_ACTION_WHITELIST, 
$this->_categories);
-        if ($key !== false && 
($registry->hasMethod('mail/whitelistFrom') != 'ingo')) {
             unset($this->_categories[$key]);


+        if ($key !== false && 
($registry->hasMethod('mail/showBlacklist') != 'ingo')) {
             unset($this->_categories[$key]);
         }

         /* Determine if ingo should handle the whitelist. */
         $key = array_search(INGO_STORAGE_ACTION_WHITELIST, 
$this->_categories);
+        if ($key !== false && 
($registry->hasMethod('mail/showWhitelist') != 'ingo')) {
             unset($this->_categories[$key]);

Result:
  1. ok
  2. ok

Regards,
Frank
