I agree sticking to the standard binary packages where possible is 
generally a good idea. But having a carefully chosen handful of packages 
built from source, where it offers a significant benefit, could be 
overall better than sticking slavishly to an overly-simplistic rule.

If your organisation is only 160 people there can not be that many 
people (2 or 3?) involved in making that policy. You should be able to 
get them all in a meeting and sort it out.

Rules are not usually written in stone. Rules may not be /wrong/ per se, 
rather they may benefit from some /refinement/.

Have mail location configured on a per-user basis via the userdb.

You can then pull individual users mail over to Maildir and update their 
mail location configurations.
