Recently updated em Client to ver 9.1.2053. No composed or replied messages are being stored in the Sent folder.
Checked Menu, Mail, Send and no option now exists to store sent messages in the Sent folder.
My em Client is properly sending messages bu no copy of the sent message is now saved.
The answer is to open Menu, Accounts, and on the General tab page, be sure to go to Send, “save copy of sent messages to “Sent” folder” select and click on that item. Save and close Accounts.
Yes, it was moved so that is available per account rather than one setting for all accounts.
But it is not available for every account, like Gmail for example, so the setting won’t be there if it can’t be changed.
