Received a message in inbox containing an email address within its body. Clicked on the address and a compose window opened. Composed message and hit Send. Outgoing copy can't be found. Checked inbox folder properties; but it contains the usual "Save copy of outgoing messages to this folder instead of Sent" -- it's unchecked because I want unfiltered message responses to messages in inbox to be saved in Sent. Messages composed via clicking an address within the body of an inbox message (other folders?) should not be summarily discarded. Yes, "Save Sent messages" is checked in Preferences. POP3/SMTP
Simply, it's not the case.
