1) Admin / Configuration / Email Accounts / Edit
Send Test Email
if the "Send Email To: " field is left blank, an exception is thrown (and caught -error msg displays on top of page, and logged). However, client side validation would probably be nicer.
Value cannot be null. Parameter name: address
2) typo in test email Subject (email received)
Subject: Your store name. Testing email functionaly.
Should be "functionality"
3) Entity Framework / Caching issue
If you install a brand new beta, then before setting up the general/default email account, you go to a product and "Email a Friend", the queued message will fail to get sent (Error logged will indicate Host problem - as expected, since no set up was done).
Then, do the proper email setup and send a test message to verify.
Then, do the Email a Friend again. It will still fail.
Debugging shows that the EmailAccount on the queued message still has properties from the incorrectly set up email account.
(You can also test this on an existing system, by breaking the working email - e.g. config / change port - Save - Send test email, and it fails. Refer to Friend will still work.)
Hopefully this is not a "system wide" EF issue.
