request read receipts

[Periko]

Hello,

We are using a Firebox II, software version 5.xx. In our outlook-express clients we activate the read-receipts option, but we don't get any. Anybody an idea where I have to search the problem ?

Are you using exchange server? IF so what version?

Hello,

No, i'm not using exchange server. I think i have solved the problem yet, thx anyway. I added in the smtp-outgoing the right headers, so it is not blocked anymore.

Hello RockChalk,

I added 4 headers :

disposition-notification-to
return-receipt-to
final-recipient
received

Did I do anything wrong by adding them concerning our security ?
