>(1)  changing priority of any queued/deffered messages 

All messages have the same priority. Deferred messages are retried
less frequently as they age, but that can be controlled by adjusting
the modification times on the queue files (e.g., using "touch") to
expire a message sooner or later than the default and/or retry a
message more or less frequently.

>(2)  changing lifetime of defered/queued message

See above.

>(3)  restricting  no of simultanious SMTP sessions from single IP address  

qmail doesn't supprot this, but you could "easily" wrap qmail-smtpd
with a script/program to keep track of sessions by IP address.

Please don't post your questions more than once. It's rude.
