my email account is with wanadoo but emclient settings are pop not imap

when setup, message store downloads 200 messages, no folders, account setting displays pop. but during setup splash screen shows both imap & pop are required. email is received, but when sent displays account not setup, setup account to continue.

Hello Gary,
sounds like your account was set up as POP3 - which is a mail protocol that only downloads your messages from your Inbox on your mail server and deletes them from it (unless set otherwise).
IMAP is a mail protocol that keeps the data synchronized with the server, which means all your folders.
For sending email you actually need to set up your SMTP server.

Unfortunately I cannot find any IMAP server settings for wanadoo servers, only for POP3. Could you perhaps screenshot your current server settings from Tools>Accounts window?
