Important concerning SMTP (Outgoing mail server)
Multiple internet-suppliers have closed port 25 in their network settings, so that customers that have internet access through these suppliers can only use their SMTP-server (outgoing mail server).
Try to send a test e-mail. If it fails to be received then you must change to the SMTP-server that your internet-supply uses.
