libcyrus-imap-perl 3.6.1-4ubuntu1 (s390x binary) in ubuntu mantic

 The Cyrus::IMAP module provides an interface to the Cyrus imclient
 library. These are primarily useful for implementing cyradm operations
 within a Perl script; there are easier ways to implement general client
 operations, although they may be more limited in terms of authentication
 options when talking to a Cyrus imapd.
 .
 The modules that compose Cyrus::SIEVE are also included, but they are
 undocumented upstream.
 .
 For more information, please see the cyrus-common package.
