passwords disapear...
system: cpanel eximmail server rejects passwords for some domains... after changing password, it is ok for a short time. but it does not accept password again after a while... how are that passwords self-reseting automaticly?
where are mail password stored? i have found only password for default users in /etc/exim/authtab (that is for username@domain mails, but not for anothermail@domain)
