c-client support programs

 IMAP (Internet Message Access Protocol) is a method of accessing
 electronic messages kept on a (possibly shared) mail server.
 .
 The UW (University of Washington) IMAP toolkit provides the c-client
 mail-handling library supporting various network transport methods,
 file system storage formats, and authentication and authorization
 methods.
 .
 This package contains helper tools for the libc-client library:
  - mailutil: utility program which helps manage email mailboxes (both
              local and IMAP/POP3/NNTP);
  - dmail: MDA (Mail Delivery Agent) for use with procmail;
  - tmail: MDA for use with the system mailer (such as Sendmail or Postfix).
