Many hosting providers' SMTP servers will only accept emails whose "From:" address is on a local domain. Any emails that do not conform to this rule are discarded silently, without any visible error message. If this happens to you, ensure that you are using a provider-based email address in the "Admin email" field. You could also set up email forwarding on the provider's side, so that any messages sent there are relayed to your preferred address.

Right. But our SMTP not only has that rule. It has a rule that "From:" should be the exact address of the authentication user.

At global configuration we have authentication user set to,for example, "noreply.limesurvey", with its corresponding authentication password.

Any attempt to send an email with a "from:" not equal to "noreply.limesurvey@mydomain.es", will be rejected.

LS sends general messages (to groups or new users) using From: noreply.limesurvey@mydomain.es, and it works fine.
Whin in a survey, LS3 tries to send messages with From: surveyadmin@mydomain.es, and won't work. Message rejected, discarded or whatever. The SMTP server won't accept it, even if it's a valid email address of the same domain.

So, is there a global configuration option for: "Allways use LS administrator email address as From: of outgoing messages" or equivalent?
