Test disabled in PR #73452

Update: We are re-enabling the test in main via PR #74545 with changes that will hopefully give us more info on the root cause.

@wfurt please check Kusto and if there is no new failure in last 5 days (since the test was re-enabled), let's close it as done (for 8.0). Thanks!

Happened once on main in last two weeks https://helixre107v0xdeko0k025g8.blob.core.windows.net/dotnet-runtime-refs-heads-main-1ec4a131ebe140708d/System.Net.Mail.Functional.Tests/1/console.bd6b838c.log?helixlogtype=result
