I want to import in CB a directory file of an alumni community, more than 7000 members. Some contacts are very old or even dead but as it is a directory, they must remain in the db. How can I manage members without email adress ?

-giving a fictive email adress? but what happens if someone tries to send an email to a member with a fictive adress ? Is it possible to exclude a domain an give an error message to the user ?

- or remove the fictive email adress after import via Phpmyadmin ? problem, there is no error message to the user when he tries to send an email to the member with a fictive adress ?

Has someone experience with this ?

Thanks
