Pfsense - Outlook the linked image cannot be displayed

[EsriSA]

Hi Everybody

From last week I had this problem in Outlook. Images pointing to websites are being blocked by my Pfsense

Errors in emails - The linked image cannot be displayed

How do I resolve this problem?

"Don't download pictures automatically in HTML email messages or RSS items"

There is also a GPO for it.

How should pfSense know that the GET for an image in a mail is coming from an email client like Outlook, so it blocks these requests ?
Are you blocking something on your LAN firewall ?
Some other proxy issue ?

@Bismarck : I don't think @EsriSA instructs (or has been instructed) his mail client to stop showing image in a mail and then looking for the phenomena in pfSense. That's doesn't make sense.
