Hello

I noticed Delivery Status Notifications are not working. Is there a way I could enable it?
 
DSNs are usually in concerns to deliverability issues. Are you stating you aren't getting bounces or are you referring to something else?

 
No, I'm talking about the option you can enable in the mail client, that essentialy just makes the recieving MTA send a "It arived in the recievers mailbox" message on successful delivery, but when I enable that in my mail client (thunderbird) I'm not getting them.

Not a big deal, but it's just weird that they're not working (mail itself is working just fine though)
 
Thank you for the clarification. I don't believe directadmin has deliverability or read receipts:

You're pointing to an ancient thread which is not the correct one. @k1l0b1t is asking for a delivery receipt, not for read receipt.
Read receipts are working, at least for incoming mail (just tested it).

The mail client is creating delivery receipts and Exim normally does not touch those headers, it's not an Exim task.

However it might have been changed in newer exim.conf as anti-spam measure, I don't know for sure. Not using it either for incoming mail. On outgoing mail I have used it sometimes and then it seems to work rarely. That is because receiving client programs can also deny to send the read or delivery receipts.

I tested with my servers.
So if I send a mail from an external email adres to my server, I get the question if I want to provide the "read" notification at least.
But I don't see the delivery notification.

You might try with a custom adjustment for exim.conf like this:
dsn_advertise_hosts = *
use at your own risk, I've read this on the CP forum as a solution. I don't know if that might already be an internal default or not.

 
ohh, so it is like disabled as an anti-spam measure, okay that actualy makes sense.
 
If I'm not mistaken, I've thought I read that somewhere in the past (backscatter filtering), because I've seen this happening on more mailservers that this is disabled.
I myself also take care that bounces are disabled too for this reason.
 
Even bounces! Damn. i'll not bother about DSN then, but disabeling bounces kinda seems crazy to me.

Why? I killed loads of spam with it.
There are some irregular flows in which spammers flood the servers with e-mails to non-existing users, with existing email addresses in the return-path, which will get the spam via our servers bounce messages.
I recently experienced it for 2 weeks with my hobby email address, which was being abused as return address and me receiving a lot of spam from a Polish server and Swiss servers bouncing these messages. No way to stop those bounce messages.

And I don't want my servers being involved in those kind of spam games. So it doesn't seem that crazy to me. ;)
 
Cool, I wouldn't suggest disabling bounce backs and sorry it seems that mail delivery reports aren't something that is available, at least what I can find. Enabling them incoming, unless I am misunderstanding, doesn't seem like what you were asking for but maybe I am mistaken. Good luck! :D
