Hello, A customer is using a system with a mailserver and a FTP-server on one machine. Now a FTP-user found out, that he can login with his FTP-username and password into the webmail (Horde/IMP), and send mail. FTP-users do not have a mailbox. Is there a way to make the authentication "not OK" for users without a mailbox? Or only "OK" for users who are member of a group? I am using Cyrus with saslauthd, PAM and the traditional Unix authentication mechanism (pam_unix.so). With regards, Paul van der Vlis. -- http://www.vandervlis.nl/ ---- Cyrus Home Page: http://cyrusimap.web.cmu.edu/ Cyrus Wiki/FAQ: http://cyrusimap.web.cmu.edu/twiki List Archives/Info: http://asg.web.cmu.edu/cyrus/mailing-list.html
