Allow Multiple HTML Signatures = no
which uses a marker in the HTML Signature to know not to add the
signature again, but with text signatures there is no way of inserting
"hidden text" in any way so that we would know not to add the signature
There is also
Dont Sign HTML If Headers Exist = # In-Reply-To: References:
so it detects when not to add the HTML signature. Unfortunately I can't
tell if the text signature has already been added, without searching the
entire message for signs of the signature, which would be really slow
and unreliable as a correspondent's email app may have re-wrapped the
text in the message, so you can't just search for matching lines. It
would be very slow with multi-line sigs especially.
So that's not really practical.
If you have any great ideas that might help solve this problem, then
give me a shout. It is easy for HTML signatures as you can look for
signs of the previous copy of the sig, but you can't do that as simply
with text messages.
