Limitations on the subscriptions

Hello,
I take care of a server with mailman 2.1.5 and numerous lists, but I administer only a small part of them.
Besides, my SMTP relay allows me to send e-mails only on a particular domain (university addresses).
The problem is that no matter how many times I repeat to administrators and users to use only these addresses, subscriptions are regularly made with other addresses, which are rejected and generate a lot of bounces.
I would like to know if there is a mean to verify automatically during the subscription process if the address is something like xxx@domain.ext...
Thank you very much,
Nicolas

You should be able to use the ban_list for this (Privacy options... -> Subscription rules -> ban_list). The operation of the ban_list has been improved somewhat since 2.1.5, e.g. In 2.1.5 you couldn't subscribe a banned address, but you could change your address to a banned address, but it should work for your purpose.
A regexp like:
^.+@(?!domain\.ext$)
will ban every address that is not @domain.ext.
