I have several signatures set up which are all in 14pt Verdana. These display as expected when I add them to a newly composed email.

However if I reply to an email and insert a signature, this always defaults to 12pt Times New Roman - regardless of what font the email I am replying to was originally written in.

Most of the emails I compose and reply to are in HTML format, not plain text.

Is there any way to force my signatures to always default to Verdana?
