I have 3 children and we want to use the family shield to save them for adult content. But we have are by the german provider Arcor (now Vodafone). We was clients since over 10 years and because of that we have an Arcor E-Mail-Adress from our provider. To send mails we need to use the smtp host mail.arcor.de - but OpenDNS block this address. Don't know why because this is not a phishing address, it is an Internet and telephone provider here in Germany.
Can I do something to unblock this address to use OpenDNS and keep our E-Mail Addresses? I am sure there is a way, please help me to find it.
Thanks in advance.
