.Sent Folder not automatically created
when setting up a new mail user, the maildir is generated and the user can successful login via mail client (thunderbird).
the problem is, when user tries to send an email, he gets an error in the mail client, that the message could not moved to the sent objects folder.
this folder doesn't exists (.Sent)
When user logs in with SquirrelMail, then this folder is generated automatically.
Is there a way to let the .Sent folder created, without the user has to login in SquirrelMail?
