Some spammers are getting very creative, what they do is subscribe to a list, pull up a list of email addresses of people subscribed to the list, and then issue spams to the list setting one of the "older" members as the FROM line.<div>

Yesterday, I set the source (<a href="mailto:irish@gmail.com">irish@gmail.com</a>) to be moderated and sent<br>
an Email saying if we see any more of it, they will be deleted. It<br>
might be a member who got compromised (fake Email IDs usually have more<br>
random characters), so I'm giving them a chance to correct the problem.<br>
So far I have only seen about 4 total, but I get a lot of admin messages<br>
about the hundreds of spam messages being blocked, so I might not be<br>
noticing all of them.<br>
<br>
The only "filters" we have on the list is 'members only' and attachment<br>
filtering. It is possible to require approval of new members, but for<br>
now that is not required (and I consider it a last resort). But this<br>
means that if a bot joins, it can send spam. I can delete the member<br>
and not allow it to ever join again, but if the bots are targeting us,<br>
fighting them manually is hopeless. In my experience, CAPTCHA works<br>
reasonably well against bots.<br>
<br>
I don't know if mailman has CAPTCHA or any other addon filters, but<br>
since I've only seen a few spam Emails every several months, I'm not<br>
going to ask Clinton to take time to work on it. However, if it gets<br>
worse, I will look into it.<br>
