Did anybody tried email? It was working very well. But I suddenly when I came back to the last project. It nearly stopped working. Only 2 emails out of thousands of tests.
The SMTP protocol seems to run on my side to completeness. The server aspmx.l.google.com answers in between correctly to MCU. But the email does not arrive to gmail anymore.
Why can be wrong?
