Email forwarding not working

It appears that certain webhosting companies have disabled the email forwarding option for the mailboxes on their server. Earlier it was very convenient for an internet user/professional to create different email ids for different users and forward them to a single email id for checking, as it was time consuming to login to the different email ids.
However in december 2015, email forwarding cannot be used for any new emails created, though older email forwarding created in 2014 seems to be working
