We've dealt with if for nearly 7 years now and only have a few months to 
go. The problems have been few. I posted this to help those make it 
through to February. I delayed moving folks from the v4 systems waiting 
for the v6 systems so as to gain a couple or few more years before EoL 
for them and for other reasons that v5 does not properly address. 
Clients don't like to be moved around. In a perfect world, email client 
programs would not have problems with these moves... but we don't live 
in a perfect world. Those problems irritate the clients and increase our 
tech support by multiple times. Heading off into a repo 1.x upgrade at 
this point is rather silly IMO.
