Too many ampersands in a Group Email Address?

Hi All,

We upgraded from GW 2012 SP2 to GW 2014 (end of May), and we are now at SP1, on a SuSE 11, SP3 server.
I have Groups in GroupWise that have worked in the past but one of them has stopped working.
I'm not sure if this has happened since the upgrade to Service Pack 1 or when we upgraded from 2012 to 2014.

I had a group that had email addresses for three different groups.
Thus, the group name was: demaximis_
