If i create also subfolders such as:

shared.domain1.testfolder.Sent
shared.domain1.testfolder.Draft

Then i create an identity testfolder at domain1 so i can send email as for
this email account.

There's also a way to map those Sent/Draft folders to the one of the
'identity' represented by testfolder at domain1  (for example when
composing email and specifing as a From testfolder at domain1) ?
