Sender address restrict only to it's own

[npc]

Hello,

While composing new email I'd like to restrict user to select(type) only his email in sender field. It's multihosting server.
Besides that I'm finding weird that no default identity is created. auto_create_user is enabled.

Because I'm trying to resolve this problem for few hours without success I'm asking for help

Regards

Ok, while updating from previous version, sql update didn't succeed, I didn't notice it than time . After fixing it everything is fine. Thank you.
