How do I solve my subscriber getting this error message: "Sent from an unauthorized email address"

Mail-List.com allows members of your list to post a message as well as approved non-members.

  • Members may be subscribed on either your regular list or Digest.
  • Non-members are people with your approval to send messages to the list.

Sometimes, people try to post from a different email address.

Example:
Susie is on your list as                   susan@xyz.com
but is trying to send email from      susan@corporate.xyz.com

How to Resolve

STEP 1 - Ask the sender to forward the error message.

The circled part of the error message below indicates what address is being rejected.

Ask your subscriber to forward you the error message they are getting

STEP 2 - Verify the rejected address

If the sender is a member, verify their address is included in your list.

For help verifying a member address, please see this post.

If the sender is a non-member, run a report to check their address. Continue to Option 3.

For help verifying a non-member address, please see this post.

 

STEP 3 - Perform an option below

Option 1 - Member > Add to your List

If the member's rejected address is not found, add the subscriber to your list.

Option 2 - Member > Add additional address

You can allow subscribers to have a secondary email address on your list. Set this address as Post Only. The subscriber will continue to receive mailing list email at their primary address, while being allowed to send new messages from their secondary address. Link to instructions shown below.

Option 3 - Non-members

Address found on report

If the report shows the same address they are sending from, please contact Mail-List.com for help.
