LM5 can't send an email

Try running this script. If you still get connection refused error then contact Microsoft and ask why your connection is blocked.

Code:

sock = require('socket').tcp()
sock:settimeout(5)
res, err = sock:connect('smtp.office365.com', 587)
sock:close()
log(res, err)

The problem is solved,  port 587 was blocked by the firewall
