I cannot send an email from a connected account when the "from" address is the email address from the connected account.
I get a "Couldn't send the following message:" error, no other details.
I'm using the IMAP servers from the connected account, "Basic" authentication and no encryption.
I cannot use the pop servers, I get a, "The POP server doesn't support features needed to download email" message.
GoDaddy is hosting the email for the connected account.
