Does the spec say how to conform to it? I mean: does "the system" have to 
support the transmission of receipts?
Most bidding rounds I've been part of only had very rough descriptions of 
what should be possible. Not exactly how. (Too detailed specs, pointing 
heavily in the direction of one type of solution provider, can be easily 
challenged!)
So, even without Dovecot supporting DSN-stuff, it would be possible to bid 
for these types of clients. The system as a whole does support DSN's, when 
MUA is conforming to relevant specs. Most MUA's support some form of DSN 
of read notification. What's more: whatever choice you make, server side 
or client side, handling of these status messages (and ways to request 
them) heavily depend on the remote party's technology as well.

So, claiming you conform to the read-notification spec can be as easy as 
saying "yes, as long as you use a proper MUA".
