===STEPS TO REPRODUCE===
1. Login to Horde
2. Add one email address to "Mail > Filters > Blacklist"
3. Activate "Preferences > Mail > Filters > 'Apply filter rules upon  
logging on' and 'Apply filter rules whenever Inbox is displayed'"
4. Send email from the same mail address which is in blacklist. Filter  
will work correctly.
5. Now add one more entry to "Mail > Filters > Blacklist" and activate  
the same in step 3.
6. Now send mails with any of the mail address which is in blacklist.  
Filters will not apply for any entry.

===ACTUAL RESULT===

Filters will not apply if more than one entry is in Blacklist filter.

===EXPECTED RESULT===

Filters should apply correctly for all entries in Blacklist filter.

===ROOT CAUSE===

As I understand the issue happens because by some logic matched  
messages are removed from list which for filter should be applied at:

\horde\ingo\lib\Script\Imap.php line 158:

                 foreach ($msgs as $v) {
                     if (!$v->getEnvelope()->from->match($addr)) {
                         $indices = array_diff($indices, array($v->getUid()));
                     }
                 }
