Merci pour ta réponse.
Ai y est... j'ai trouvé 
Je dois donc mettre pour le serveur sortant, celui de mon FAI...
Avec celui de yahoo, cela ne passe pas.
Bizare tout de même...
Je pensais que FAI et serveur mail n'avaient rien à voir...
Voilou!
Qui sait, cela pourra peut-être aider quelqu'un

Error Message: "The connection to the server has failed. Account 'mail.yourdomain.com', Server: 'mail.yourdomain.com', Protocol: SMTP, Port: 25, Secure(SSL): No, Socket Error: 10051, Error Number: 0x800CCC0E."
Cause/Description: The reason for this error is because many ISP's (Internet Service Providers) are blocking "Port 25" which is the port used to send email. They do this as a security precaution to protect against "spam" (unsolicited email). More and more ISP's are doing this everyday (none of us like spam!). Here are just a few of the major ISP's that block Port 25: Earthlink/Mindspring, AT&T, MSN, Verizon, Bellsouth, Roadrunner, and most cable and DSL companies.
Solution: The way around this is to set your SMTP settings to those of your ISP's. For example: "mail.cox.com" rather than "mail.yourdomain.com". After doing that, you will be sending mail though your ISP's servers rather than ours. Keep in mind that nothing else changes in the way your mail is delivered. Your "from" address and your "reply to" address will remain the same.
You will need to contact your ISP and ask for the "SMTP or out-going mail server address", to find out exactly what to replace mail.yourdomain.com with.
