The invalid email addresses extracted from the text file, along with the reasons for their invalidity, are: 1. **foo-bar@example.com** *Reason*: Domain does not accept mail (nullMX record). 2. **noperson628@gmail.com** *Reason*: Recipient address rejected (user unknown). 3. **againredacted@example.info** *Reason*: Local mailbox unavailable (user not found). 4. **xsz032by05wfk5jpe@mail4you.biz** *Reason*: Local mailbox unavailable (user not found). 5. **redactedfinally@gmail.com** *Reason*: Email account does not exist (typo or non-existent address). --- **Note**: The address **wontsay@bestpay.com.cn** was excluded because the error ("suspected spams or account/IP exception") suggests a spam-related rejection or IP block, not necessarily an invalid or non-existent mailbox.
