Test email forwarding
After you have set up email forwarding and verified the recipient address, you can test the email forwarding by sending a message to the new email alias.
Note: If you send the email from your existing recipient address, many email programs (such as Gmail) will automatically put the message into your Sent mail folder, and the message will not show in your Inbox. To see your email in your inbox, send it from a different address, or check your Sent mail.
For example: If you forward the alias firstname.lastname@example.org to email@example.com, a message sent from firstname.lastname@example.org to email@example.com may only appear in the Sent mail folder of firstname.lastname@example.org. To see a message in your inbox, send the message from another address, or have a different user send the message from that user's email.
