You want to abort the transaction on the callback? What for? You could
have aborted it earlier.
Of course, in a function you could save the mails you are going to send
and register a callback for the actual send, or discard if the
transaction is going to abort. But you have to be very careful not to
do cause errors during the sending of the mails ...
All in all, I think it's easier to do it with NOTIFY or a cron job.
