Problem you are trying to solve

User wants to send a message to two recipients and performs the following steps:

1. Open screen to compose a new message (To field has the focus)
2. Enter text "[email protected] [email protected]"
3. Change focus to another field

K-9 Mail does not recognize two addresses separated by a space. It will try to parse it as one address and display an "Error parsing address!" error.

Suggested solution

Support "completing" an email address using a space character.

This is a bit tricky because a space might also be part of the display name, e.g. "Firstname Lastname [email protected] [email protected]".
