[Mailman-Users] Restricting subscribers

[Adrián Márques]

Hello there,

I'm new to mailman, trying to set up a few lists and would like to 
restrict subscribers to those with email addresses from a particular 
domain, for example, only addresses of the form <user>@foodomain.com.
I've seen that a moderator can accept subscribers, but can the filter 
described above be automated?

I'd highly appreciate any responses on this; I've looked around but 
couldn't find anything.

Thanks in advance.

Regards.

Adrián.
