The entries here are quite simple, kowning what to enter is a bit more difficult since these are specific to yuor SMTP host.
1, What has your ISP told you to use for the SMTP host name.
2. What has your ISP told you to use for the port?
3. Does the ISP require you to use SSL or STARTTLS? (Special tab)
4. Does your ISP require the use of Authentication? (Special tab)
I tested smtp.wannado.fr on port 25 and it responded
220 mwinf2814.orange.fr ESMTP **************************
ehlo thomas
250-mwinf2814.orange.fr
250-PIPELINING
250-SIZE 20971520
250 8BITMIME
So I suspect that the host name smtp.wannadoo.fr using port 25 should work in the SMTP setup.
