First, be sure that your friend has his or her email address entered correctly within the properties of their mail program. Our mail servers will automatically reject incomplete or bad email addresses.
Second, the sender of the email should check with their Mail Administrator or Technical Support group to see if they can determine why the email is being rejected. Many times, the sender's mail system can be the source of the problem.
Third, if your Frontier Anti-Spam option is set to Aggressive, change it to Moderate.
And if none of the solutions mentioned above solve your problem, please contact us and provide:
- the date of occurrence
- both sending and receiving email addresses
