The new work account started with email tests.
I sent a message from Gmail to the support address. The reply came back:
This works.
Another message arrived from my new work address with an instruction:
Reply back.
So I did.
That gave me both directions. Personal mail reached support. Work mail reached Gmail. The reply stayed on the thread and made it back through the same route a real conversation would use.
A configuration file loading without an error was not enough. I wanted the message to leave one system, cross the public edge, land in the other inbox, and return. Each successful step removed another place for the problem to hide.
The company names were messy. The offer used A-Trust. The operating mail domain and several people used Profit Services. I knew where to show up and which systems needed work, but the messages do not explain the corporate relationship cleanly.
Everything else kept moving too. I was looking at used furniture and helping coordinate a puppy coming to Colorado. A new account did not pause the normal weekend.
The useful result was small. Two addresses. Two directions. One reply all the way back.
The account was active. Someone answered from the other side. That was enough for Saturday.
The subjects were tiny because the message itself was the test. One went from Gmail to support. Another came from the work domain and asked for a reply. I sent it back and watched the thread return.
The offer had been paper. These were real addresses moving through a real mail system, even if I still did not have a clean explanation for the two company names.
