We've updated CiviCRM to 4.6.3. Since then, CiviMail has stopped working. When we log in, the following warning pops up:
"Warning: Outbound email is disabled in system settings. Proper settings should be enabled on production servers."
We set it up correctly in Email settings both mail() and SMTP, and in both cases the test mail is sent OK according to the popup window (view attached file). But it does not get delivered so we believe it isn´t really sent.
We´ve checked if we've been blacklisted or anything but we haven't.
Afterwards, we've tried writting random letters and numbers in SMTP server and SMTP user, and the popup stills says that the mail has been sent.
We would appreciate any help to find a solution.
