It's very strange but I can't set the email server adress in the module "Mail Sending Options" (via SMTP to remote mail server)…the answer is always the same : Failed to save mail sending options : Missing or un-resolvable SMTP server hostname
and Im'sure that the adress I entered is correct and resolved…

An idea ?
