If you use any other MUA, it doesn't check validity of the recipient - 
it just sends message to someone smarter ( SMTP server ). If server
fails - it sends info to the sender and the administrator.

If you want IMP to be smarter than averaage MUA the solution is to add 
mailaddresses vailidity check routine and call it every time "Send" button 
on compose screen was pressed. It can be a simple Javascript function
with one regexp.

IMP typical (only model ?) installation is that both MUA ( IMP ) and MTA 
( postfix/sendmail ) is on the same machine - it MAY look as the problem
is specific to IMP because of such model. In fact it can be the MTA problem.

I traced both horde/imp2 and horde2/imp3 sourcetrees looking for something
which could behave in the manner described by you. Are you sure IMP sends 
message to postmaster, not MTA ? Can you post a log excerpt ?
