Hi Markus,

I was trying to write wannabe-joke / philosophical / theoretical 
comment. It seems that I failed :-(

What I tried to say is something like this :
If some character is forbidden for usage in file or folder name in your 
OS who stands in your way to "escape it" or use mappings e.g. use 
9ca6aead2310a010cf445099d8c731490329f9af  (result of 
SHA1('Markus.Winkler')) instead of Markus.Winkler if '.' creates a 
problem. You need just one additional file to record mapping info and 
some CPU cycles / IO operations  to do mappings every time you need to 
access it (hence mentioning benchmark tests). Yes, admins would "love" 
that and yes, this comment had no real value for dovecot users. Sorry.

Have a nice day,

Ivo.
