Two mail signatures at the same time

We have a disclaimer text at the bottom of our outgoing email messages. This is done by the use of a mail policy, message disclaimer. Works oke.

Now we also want to add a company logo at the top of outgoing email. So a company logo at top of the message and a disclamer at the bottom.

How can this be done?.

I looked for adding a HTML file as signature in the preferences of my mailfile. But this has two cons:

  1. Can only be added at the and of the message

  2. Has to be reachable on the filesystem. (Should be reachable in a notes dataabase).
