Hi

How can I tell ruby-talk to not send me copies of the messages I send to  
it?

No. It’s distributed to all list recipients right after its arrival  
to the list server. If you have any problematic contents, all we can  
do is removing the mail from the list archive.

Alder, since you are on Gmail it’s probably not too hard to create a  
filter that will delete your messages to the list.

Kind regards

Careful with this though, because it’ll trash both copies.

Hi

Thanks to everyone who answered this thread.

I’ll try solving the problem by adding a filter to my Gmail account.

Regards,  
Alder G.

Ok, an update:

It appears Gmail doesn’t provide any way to filter those messages.

Gmail allows filtering based on three headers only:

1. From
2. To
3. Subject

Beyond those headers, Gmail only allows to filter by positive and  
negative text search on the message body.

Since the copies sent by ruby-talk are identical to the original sent  
message in all the above 3 headers, and also of course the body,  
there’s no way to distinguish and selectively remove copies by using  
the current Gmail filters.

So it appears the only way to avoid message duplication if you have  
Gmail is by using a more sophisticated email client and accessing  
through POP3. Which is too bad, since the web client is so much more  
comfortable and portable.
