I sent another test message from Gmail to my SimAuthor account on February 14. The reply from the work address said, "Got it."
That exchange was part of a longer run. The archive contains similar tests on January 16, January 20, January 25, January 30, February 1, February 2, February 4, February 11, February 12, February 13, February 14, and February 15.
Some messages went from Gmail to SimAuthor. Others came back from SimAuthor to Gmail. Most had the subject "test" or "RE: test." Their bodies were equally short: "Good to go," "Yep got it," or another confirmation that the message arrived.
The repetition means I was not checking a single one-time delivery. I was verifying the path across different days and changes. The message headers also preserved the two identities: a personal Gmail address and my Network Administrator signature at SimAuthor.
The surviving mail does not identify the configuration being changed. I cannot say whether this was an Outlook setup, mail routing, DNS, spam filtering, forwarding, or another part of the environment. Several messages mention Microsoft Outlook through their formatting, but that is not enough to name the project.
At SimAuthor, I supported the network and a mixed Windows and Linux environment. Email depended on several pieces outside the mail client, including DNS, authentication, firewalls, and the connection between the office and outside services. A successful test in both directions narrowed the problem even when it did not explain it.
There is no detailed ticket in this archive and no final note saying the work was complete. The last messages simply continue to arrive.
The useful result on Valentine's Day was two words. The message left Gmail, reached SimAuthor, and the reply came back: "Got it." More tests followed the next day, using the same two accounts and the same short confirmation.
