Postman was very useful !
@mattyrob
All working now . Thanks a lot
Subscribe2 is a great plugin !
Just installed Postman plugin (smtp mail) to solve the limitation of wp-mail.
I will restore my total 290 subscriber list to Subscribe2, and make a real post on my blog tomorrow to see if it works, at least for the Public Subscribers.
At the moment I do not have much hope for the registered subscribers !
Me again 🙂
I did reinstall again Subscribe2, and now I can see (through WP Mail Log) that emails are produced (and received) by my 2 Public Subscriber addresses.
No emails are produced for Public Subscribers !
