Mail::IMAPClient (IMAP client library for Perl)

Mail::IMAPClient is a Perl module that implements the client side of
the IMAP4 protocol. It lets Perl scripts connect to an IMAP server,
log in, list and select folders, search for messages, and fetch, copy,
move or delete them.

Optional authentication methods need extra Perl modules:
perl-digest-hmac (CRAM-MD5), Authen::SASL (DIGEST-MD5) and
Authen::NTLM (NTLM). The last two are not on SlackBuilds.org.
