Negative SMTP response to data-dot and Blocked MTA-BLOCKED

[Varghese, Daniel]

Hi All,

We have postfix node in which we configured amavisdfeed (in main.cf) as content_filter=amavisfeed:[127.0.0.1]:10024  the amavisd version we use is  amavisd-new-2.6.4 (20090625)

In Amavisd.conf the re-injection of mail to POSTFIX configured as

$notify_method  = 'smtp:[127.0.0.1]:10025';
$forward_method = 'smtp:[127.0.0.1]:10030';

Many of the mails get stuck in the deferred Q, in the maillog file I have following errors for such mails, can someone can help to understand why this error occurs intermittently?
