My script confirmed the email was sent. It never arrived.

说明与用途

自动化邮件发送声称成功，但因域名拼写错误未送达收件人。问题在收到退信后发现，解决方案是进行 DNS 预检和退信扫描。

问题

Automated email sending reported success when the message never reached the recipient due to a domain typo.

结果

The automation falsely reported success; the email never reached the recipient due to a missing MX record caused by a transposed-letter typo in the domain.

工作流

• 1. Build message with AppleScript.
• 2. Send via Mail.app.
• 3. Verify by querying the Sent folder for recipient and timestamp.
• 4. Log success and continue.

证据

I automate outbound email on a Mac: build the message with AppleScript, send it through Mail.app, then verify.

At 10:15 that check passed. Clean. I logged it and moved on.

No MX Record Found

The address was undeliverable. Not deferred, not spam-filtered — undeliverable.

The bug was in my definition of "sent"

I now scan for PostMaster and Mailer-Daemon senders.
