Sending mail from non default identity hangs on copy to sent folder and does not write to draft folder.

I have a non default identity which has the sent and draft folders set to the default identity. When I write mail from this non default identity no draft is written. When I send the mail it is sent but hangs copying the mail to the sent folder.

You might get some suggestions if you post screenshots of your incoming server setting, the identity setting, and the SMTP server setting pane.
To clarify, this is an non-default outgoing server identity within the default account.
