Nautilus Send-To Plugin - Thunderbird/Seamonkey/Etc

[NoOp]

When in Nautilus & when you right click on a file there is an Send to...
option. The default is to send the file as an attachment using the
Evolution email client. For the 5% (my guess - no facts whatsoever) of
Ubuntu users that use Evolution as their email client this works fine.
For the rest that use Thunderbird or some other email client, this
doesn't work.

The following are related to Thunderbird & how a few
users resolved it:

So now that someone has figured out the key to fixing the problem for
Thunderbird, does anyone have suggestions/details on how to change this
to other email clients such as Mozilla Seamonkey?
