sasl_passwd_check: shadow
If you don't want your password check to be the default sasldb, you must specify which one of PAM, kerberos_v4, passwd, shadow you wish to use. If PAM is the authentication you desire for example, you would type:
sasl_passwd_check: pam
instead of the line above
This list of instructions will set up all the directories necessary for imap.
