Topic: DSN not working ?

==== Provide basic information to help troubleshoot and get quick answer ====

Debian 6.0.2
iRedMail-0.7.3

Hello,

I'm new to iRedMail. I already implemented it on two mail servers and managed to fix all issues I had but I have a problem with Delivery Status Notification (DSN) not working - I want all senders who have that flag in their emails to receive a success DSN.

I read everything in google I found with no luck.

Please help me solve this issue.

Re: DSN not working ?

What flag? What kind of email and DSN do you expect?

Thank you for the prompt reply.

As you know there is a delivery status notification flag in every message - the client decides if to raise the flag or not.
Installation of iRedMail makes some configuration changes in Postfix and it returns read request status but doesn't return DSN (delivery status notification) when such flag is raised.

That's what I mean - I need a way to make DSN be sent out to the sender on successful delivery.

Re: DSN not working ?

I'm afraid that iRedMail (Postfix) doesn't support this feature. You see this feature in Microsoft Exchange, right?

Re: DSN not working ?

DSN is working for me on iRedMail. Are you using Postfix 2.3 or older? (older versions don't support DSN).
It is turned ON by default, and it's working.

Debian 6.0.2
iRedMail 0.7.3
Postfix 2.7.1

I'm using Postfix 2.7.1
I know it's ON by default because I already implemented postfix alone and had no problems with it.

I think the problem is somewhere in the colaboration between postfix, amavisd-new and spamassassin may be ?

Can you help me with this ?

Re: DSN not working ?

Did you try finding related log in Postfix/Amavisd/Dovecot log file?

I didn't find anything strange in the log files of Postfix, Amavisd and Dovecot.
I think there is some restriction in the configuration of Postfix or Amavisd but I can't find it.
I know for sure that if I install postfix from scratch and configure it myself the DSN is working perfectly.

It's a good idea to compare their configrations to figure out why DSN on iRedMail server doesn't work.

I did this and I couldn't find anything wrong - that's why I think that the problem is not in the postfix itself or it's configuration but something to do with the colaboratioon with amavisd and dovecot may be ?!

Re: DSN not working ?

DSN are processed by Postfix only and DSN responses are sent only by Postfix. Amavisd and dovecot don't have anything to do with this.

Thank you maxie_ro.

This was usefull. There is nothing in the postfix logs about a generated DSN message.
I think there is some configuration parameter which prevents DSN from being generated and sent back.
When I configure postfix by myself everything is working but in iRedMail default postfix configuration there are many more configuration parameters which I've read about and there's nothing about DSN but may be the collaboration between them stops DSN ?
