sender delivery status notification not working

[pritam raote]

Hello,

* DSN(sender delivery status notification) does not work on my box running
postfix.
* the version of postfix on the non working box is postfix-2.8.7-1

In Mozilla Thunderebird
write message --> options --> Delivery Status Notification

* Read this didnt help much http://www.postfix.org/DSN_README.html
* The qmgr should pass the message to bounce daemon to send the DSN to the
sender but this does not happen.

DSN works only if:

1 - The POSTFIX SMTP server sends the DSN announcement to the REMOTE
SMTP client.

2 - The REMOTE SMTP client (Thunderbird) requests DSN support.

To find out if (1) and (2) happen, you need to report the SMTP
commands and replies between the POSTFIX SMTP server and the REMOTE
SMTP client (Thunderbird). You can anonymize the email address.

There is no DSN announcement, therefore, the mail client will not
request delivery status notification.

DSN support is available with Postfix 2.3 and later. To view
Postfix settings use:

$ postconf | grep smtpd_discard_ehlo

$ grep smtpd_discard_ehlo /etc/postfix/master.cf

* Yep the mistake i did was that i was grepping for smtp_discard instead of
smtpd_discard

postconf | grep smtp_disc
smtp_discard_ehlo_keyword_address_maps =
smtp_discard_ehlo_keywords =

postconf | grep smtpd_disc
postscreen_discard_ehlo_keyword_address_maps =
$smtpd_discard_ehlo_keyword_address_maps
postscreen_discard_ehlo_keywords = $smtpd_discard_ehlo_keywords
smtpd_discard_ehlo_keyword_address_maps =
smtpd_discard_ehlo_keywords = silent-discard, dsn

* Sorry for all the trouble and thanks for the replies. You guys rock.
