Hi,
ist there a way to remove sensitive information from the Email Header ?
Background: If you send Emails from mobile networks, and you have alle "receieved from" informations in the header - and the receieving Mailserver makes a deep header scan - it's high possible, that the message is marked as spam - thats because the mobile devices typical dynamic adresses, which are often listed on blacklists.
WIth postfix it's easy to make a rule for authenticated Mails to strip all receieved from headers - and replace them with another heather - like "X-Recieved: From Authenticated User" to prevent such false positives.
If it's not implemented - I think it should be a feature for the next version.
SMTP-Out
X Replace Received From headers fot authenticated users with X-Recieved: ________own text______________
regards
