Does qmailtoaster support *Bounce Address Tag Validation*
No.

If yes, how do we activate it and if no, is there any plan to implement
it in near future.
No plan in near future. That's not to say that plans won't change.
Personally, I like the idea. There are a few problems with it though:
http://en.wikipedia.org/wiki/Bounce_Address_Tag_Validation#Problems
The ezmlm problem is pretty much a show stopper at this point for QMT.
At some point though, I'd like to see mailman replace ezmlm (I use
mailman instead of ezmlm myself), at which point BATV might be feasible.
I did come across this patch for it:

I've included this for posterity as much as anything else.
While backscatter is certainly undesirable, it can occasionally serve
notice that an account password has been compromised. This happened
recently to one of my users, and I'm not sure how I would have noticed
except for the backscatter that came in. I'm lucky the IP wasn't
blacklisted.
I think it would be prudent to implement a mechanism such as a
qmail-remote throttle (mentioned in a recent thread here) to control
outbound spam before implementing something which will drastically
reduce backscatter.
Thanks for bringing this up, Amit.
