Error sending mail

[beeson76]

Whenever I try to send an email I get an error. 

BAD * OK.  Must create a mailbox before append.

What does this mean and how do I fix it.

Thanks

It means the mail server lied to my app about having a server side folder for drafts / sent messages.

Let's make the app use only local storage for drafts / sent:

- Long press the account
- Choose Options and Folders -> Folders
- Scroll to Drafts (or whatever the server calls it), it should say "Sync with [ Drafts ]" below. Tap, choose "Do not sync".
- Repeat with the Sent folder.
- Back out to the main screen, try sending a new test message.
