I am still confused about image files in the Signature.
When an image file is placed in the signature the sent file will have an MIME file attached in the email thus almost doubling the email size.
When there isn't an image file in the signature, there isn't an MIME file sent and therefore the size of the email stays small.

Why is this? Is there a way to place our logo in the signature without doubling the size of our outgoing emails?

Just wondering,
