I know that with SMTP-before-POP only my users can send mails from my server. but they still can have a different mail adress in the "FROM:". how can I check that? If I can check that... how can I check it if a user is allowed to send a mail from an alias (from qmail/alias)? f.e. [EMAIL PROTECTED] should also be able to send mails from [EMAIL PROTECTED] and user is an alias. thanks for answers Joel
