NAME
       mailauth	 - manipulate alternate authorization database for Post Office
       Protocol (POP), Internet	 Message  Access  Protocol  (IMAP),  and  APOP
       users.

SYNOPSIS
       /usr/sbin/mailauth [-init] [-convert] [-list [-type POP | APOP | IMAP]]
       [-delete name] [-user name [-type POP | APOP | IMAP]]

OPTIONS
       Initialize the database. You must be  superuser	to  use	 this  option.
       Convert	an existing APOP only database to the new format.  You must be
       superuser to use this option.  Used to list the entries in the mailauth
       database.  If no type is specified, all entries in the database will be
       displayed.  The display will consist of one column corresponding to the
       username	 and  another column for the type of user. If a type is speci‐
       fied using the -type option, only entries for the corresponding type of
       user (POP, APOP, or IMAP) will be displayed.  Used by the system admin‐
       istrator to either add a user to the mailauth database, to  change  the
       password for the user, or to change the type of user. The administrator
       will be prompted for a new password and	then  a	 verification  of  the
       password.  If the type is not explicitly specified and a previous entry
       does not exist, then it will default to APOP.  Used to delete the entry
       corresponding to name from the mailauth database.

DESCRIPTION
       The  mailauth program allows a POP, IMAP, or APOP (an alternate authen‐
       tication method for POP) user to change the secret value used to gener‐
       ate  their  authentication credentials. In addition, both the superuser
       and the user pop may use this program to either add or remove  a	 user,
       or  to  print  public information from it.  Only the superuser may ini‐
       tialize or convert the database.

       A user can change their own passwords or add themselves to the mailauth
       database by entering the mailauth command.  If an entry already exists,
       the user is first prompted to enter the old password.  If the  password
       does  not correspond with the one in the database, the transaction will
       be ended. Otherwise, the user will be prompted for a new password and a
       verification  of	 the  password.	 The user is not allowed to change the
       type of user they are. For example, they cannot change themselves  from
       a  user	using the APOP command during the POP Authorization State to a
       user using the Internet Message Access Protocol (IMAP).	 If  an	 entry
       does  not  already  exist in the database, the user will be added as an
       APOP user.

       Under normal usage, mailauth prompts for a new secret,  just  like  the
       passwd program.	It then updates the POP authorization database accord‐
       ingly.
