[Mailman-Users] subscribing with settings maintained

[Web Dev]

Hello,

Please help. We are transferring a mailing list and would like to be able 
to keep the users' mail delivery settings in place when we upload (mass 
subscribe) the addresses. Can someone provide the command to do this?

This format doesn't work:
    email at someaddress.com,digest
because the program thinks it is a Hostile Address (illegal characters)

TIA

Regards,
