Hi all,

I have content filter that drop inbound email that contains images files attachments(.gif, .png, .mpeg, .bmp, mpeg).

This filter also block logo in email signature.

When Microsoft outlook users send emails, the email logo signature is sent as attachment named image001, image002, image00n and the attachment is blocked by ESA.

How can i drop image files (.gif, .png, .mpeg, .bmp, mpeg) but allow specific filename (image001.gif, image002.gif)?

Thanks,

Marco

Hello Marco,


As you're using content filters you'll need to create an additional filter to put it 'on top' of the block one.

The top filter will be if attachment filename -> equals -> (image001\.gif|image002\.gif)

Action -> Skip Remaining Content Filters

And deploy this filter.

Ensure that this filter is ontop of the drop image file filter in terms of the order.

It will be best to keep these two filters last within the content filter list.

I hope this helps.

Matthew
