All,
Due to the DMARC mitigation action ‘Replace From: with list address’, it happens often on my lists that someone sends a message to a mangled address, hoping that the message goes to the person listed as the sender. This happens mostly because the mail clients collect previous addresses and use them when as type-ahead candidates for new messages, which may be unrelated to the lists.
For example, say the mail client captures my address as
“Allan Hansen via <listname>” <listaddress>
then later, when the person wants to send a message to me, the type-ahead puts this string in the ’To:’ field:
“Allan Hansen via <listname>”
and, to make it worse, the actual email address, <listaddress>, is often hidden.
The result is that the email gets sent to the list instead of to me, together with (often) personal and (sometimes) embarrassing information.
Is there a way to reject messages sent to recipients where the name part of the recipient is of the above format, i.e.,
"Allan Hansen via <listname>"
In other words, filtering is done on the name part of the recipient, not the address part.
Should I get onto the other list to request this as an enhancement?
Yours,
Allan
