That's no surprise.
I should have anticipated this, in fact, but first,
to make sure that the plugin does something that it should,
could you try inserting instead a made-up header,
e.g. "X-Testing: ignore"
and then send a message to yourself?
Does the message get delivered back to you
with that header included, or not?
(it might require the "Blah blah" button to see it).
By the way, does your _outgoing_ message
display the inserted header at all?
(it doesn't in the Windows versions,
where "extra headers" are not visible to the sender,
but only to recipients).
Now, to see whether anyone else can do what you can't,
would anyone who has any other kind of "extra headers"
function working care to attempt using it
to add a "Bcc:" header to themselves, say,
and see whether that has any actual effect at all?
The Windows versions of Eudora, by the way,
also have a built-in "ExtraHeaders" option,
which works fine for a made-up "X-Testing: ignore" header,
but it does nothing at all in response to an attempt
to add a "Bcc: myself@[EMAIL PROTECTED]
" header.
Why not?
Because SMTP does not pick up the names of recipients from headers!
SMTP servers are instead told to whom to send messages
by means of *commands* (specifically RCPT TO),
which are all given to the SMTP server first,
before even the first header line starts to be transmitted.
The header lines of the message to be sent are then lumped
together with the message body as one "blob" of continuous
data, to which minimal attention is typically paid,
because the preliminary *commands* have already
told the SMTP server everything it needs to know
about delivering the message.
For a clear and simple explanation of all this, see:
http://db.glug-bom.org/lug-authors/philip/docs/mail-stuff/smtp-intro.html
Therefore, unless Eudora were expecting someone
to try to sneak in an "extra" _addressee_ header like "Bcc,"
which it already provides anyway, an "extra headers" function
will not succeed in making Eudora issue additional preliminary
"RCPT TO" commands to the SMTP server, before transmitting
the "data part" (headers+body) of the message,
hence the attempt fails.
So, this might actually have been the plugin you remembered existing, but
I'm sorry that it may be unable to do the thing you wanted it for :(
