The risks are dependent on how effective your antispam measures are. If 
you find that your institution is still delivering a high amount of spam 
to user inboxes, it might be wise to continue the ban on autoreponders.

If you don't get much spam, sieve vacation is suitable. Providing a 
usable frontend for ordinary users is the real challenge.
