Requests a message delivery notification

[zimny585]

Hi
I installed on my server computer mail server (hmailserver 5.4.2 - Build 1964) and new Roundcube 1.0.3. Everything works well, just i have a problem with requests a message delivery notification. Wen i select checkbox Return receipt and i send no matter to whom ( eg. [email protected] to [email protected], [email protected] to [email protected] ) no window appears with information to send notyfication. Does not send even when pointed to automatically send (config defaults.inc.php).
Please help and information about what is wrong with my mail.

Sorry for my poor English


PS I installed SquirrelMail to see if the same happens but everything works here (windows appear to ask whether confirm read )
