amavis Delivery status notification(DSN) failing
in [Postfix]
|
From: "Sharma, Ashish" on 9 Apr 2010 09:45 Mark, Accepted your point, but I am actually doing what you have suggested already. Maybe the proof lies in the fact that my custom content filter is working fine when amavisd is not used and postfix is directly communicating with my component. I am not receiving such problem in that case. Is it because postfix is little lax in enforcing smtp for content filter?

You need to fix your code, or better, use code that already works instead of re-inventing SMTP badly. Wietse

Andreas, Thanks for the suggestion, On comparison I found this http://code.google.com/p/subethasmtp/ to be more appropriate(lightweight and easy to use for a simple postfix content filter) than the heavyweight Apache James.
