mailchimp does not allow to import so called role addresses via the webinterface.
office@ and the like can't be imported but need to be inserted manually.
(see What role addresses does MailChimp block)
this script allows to import subscriptions even though some or all emails are role addresses using the mailchimp API MCAPI.
chimpimport --help for usage information:
