Usernames

[Charles Bronson]

Maybe this is the wrong list to ask this on. If so, please accept my appogies 
and kindly redirect me.

I noticed in Shrike and now Severn that usernames can only be lowercase (at 
least in the GUI tool, I haven't checked useradd). I am wondering why caps are 
no longer allowed?

Thank you.

Maybe because various MTAs map uppercase to lowercase and so having both
"user" and "User" will lead to confusion (who will get
)? Just a guess.

Any MTA which does this, at least for outgoing mail, is broken. RFC2821
requires case-insensitivity only for PoStMaStEr@, anything else is up to
local policy at the receiving site.
