My first post on this community and no previous experience on mail systems, so I beg for some indulgence.
Do you know if it is possible to remove x-headers added by Kaspersky Security for Microsoft Exchange? Or at least change the values of the x-headers.
I’m interested in doing so to the messages sent out of the organization.
X-headers expose too much information to the outside world, starting from the used antivirus/antispam product used.
I have used Exchange rules to delete x-headers or change the value. It works sometimes, others do not:
- Removing x-kse-antivirus-attachment-filter-interceptor-info or x-originating-ip works OK.
- Changing the value of X-KSE-ServerInfo does not work.
But creating a rule for each x-header will be a bit of overheating the mail server. So I would prefer to manage the issue within Kaspersky, if possible.
I have searched for information on the subject with no results.
Am I asking for something stupid maybe?
Thank-you very much
