No, it's not your LDAP entries.

There are a couple of things going on. First, we were returning a  
comma delimited email list. Some clients were ok with that, while  
others tried to parse it into a single email address, and would either  
fail completely or would only include the first email.

Secondly, while trying to correct the first point by using the RFC  
5322 standard "group" syntax, I discovered that clients also had  
trouble with this form as well. For example, iOS will complain that it  
doesn't "look like" an email address, but will still let you send the  
email. Nine, on the other hand will flat out refuse to send the email.  
While stock Android seems to only include the first email.

I'm not really sure what to do about this. I leaning towards  
implementing the correct RFC 5322 way of representing the group and  
let the client developers worry about fixing their end. At the very  
least, things will not work just as much either way. I have access to  
a real exchange server VM for testing, so maybe if I find the time  
I'll set up a GAL and see how these clients (mis)behave against  
Exchange and at least try to match that.
