[Mailman-Users] Email from Listname

[Fitzpatrick, Ted]

Hi,

A hacker recently broadcast email to a discussion list by setting the "from:" header to be the name of the list, e.g., listname at emaildomainname.ca.gov<mailto:listname at emaildomainname.ca.gov>

What's the best way to resolve this issue? If I block incoming email from this address, will that interfere with Mailman's normal operations?

Thanks,

Ted
