Title: Missing sender on read acknowledgement
Post by: leake2019 on October 06, 2019, 12:37:53 PM
I have installed RC version 1.3.10 on a Centos 7 PHP7.3 environment. I am able to send/receive OK EXCEPT when I send a read acknowledgement when I receive the following error message:

SMTP Error: Failed to add recipient '[email protected]'. to send email from a blank sender, enable blank senders (Code: 550) in /var/www/html/roundcube/program/lib/Roundcube/rcube.php on line 1667 (POST /webmail/?_task=mail&_framed=1&_action=sendmdn)

Any help in rectifiying this error would be appreciated.

// According to RFC2298, return receipt envelope sender address must be empty.
// If this option is true, Roundcube will use user's identity as envelope sender for MDN responses.
$config['mdn_use_from'] = false;

Thanks for your reply Alec. When I set 'mdn_use_from' to true and it ALWAYS automatically sends a read achnowledgement regardless of what 'mdn_requests' is set to (if '0' it should ask user if read acknowledgement should be sent). Is this by design or is it a bug?

That would be a bug, but I don't think that's the case. These two config options work on completely different level.
