Most probably he wanted to enable his users to send emails via his mail 
server using port 587, because some may have blocked access to port 25.

Proper solution is to open additionally port 587 and require users to 
authenticate in order to send mails through the server. If it is too 
complicated in postfix, admin can simply map port 587 to 25 - most 
probably that would work well.
