Hello Experts,
This is a VB6 very small app that has been working fine for decades
the nice things users like about it are that it shows a percentage number when transmitting... and its pretty fast.

For some reason, it started showing the following message
" 503 This system is not configured to relay sender from an anonymous sender. "

Please your advice,
