Okay, Andy, let me try to explain.
I have both an iMac and an iBook, and I use the same email account on both. I want the iMac to contain a complete archive of sent and recieved email. Recieved is easy - I simply set the iBook not to remove emails from the server.
To get the email sent from iBook to appear in iMac's sent mail folder, I've told the iBook to automatically Bcc all mail to a dedicated address on my own domain (archive@xxxxxx.com) using a terminal command I got from another thread on here. (See my earlier question here:
http://discussions.apple.com/thread.jspa?threadID=1444967&tstart=0)
That means the email will soon turn up in
both inboxes unless I do something about it. On the iMac I want it moved to sent mail, so I've set a rule on the iMac that recognises these emails (if Envelope-To contains xxxxxx.com then move to sent mail). This works fine, but I
don't want it to play the new mail sound. On the iBook I don't really need to see it at all, so the rule is set to delete the message on the same criteria.)
Is this making sense so far?
Anyway, I set the preference on the iBook to play no sound, then set the rule to delete these emails (then stop evaluating rules). The next rule is "any message - play sound".
The result was that when I sent from the iBook I seemed to get the sound set by that rule immediately followed by the normal sent mail "whooosh".
Love it if you could help, but it isn't that important in the great scheme of things!
