Hi,

running Postfix 2.4.5

According to http://www.postfix.org/pipe.8.html it is possible to define a 'user:group' in a pipe entry in master.cf:

       *user*=/username/:/groupname/
              Execute the external command with the rights of the
              specified /username/.  The software refuses  to  exe-

This text could be more precise: Postfix executes the external
command with the user ID and group ID of /username/.

              cute  commands  with  root  privileges, or with the
              privileges of the mail system owner.  If  /groupname/
              is  specified,  the  corresponding group ID is used
              instead of the group ID of /username/.

Note, it says "the group ID of username" meaning it uses only one.

thanks for your answer. Is there a way to file a 'request for enhancement' to ask for support of multiple groups in a future version of Postfix?
