libnet-imap-simple-perl binary package in Ubuntu Bionic amd64

 Net::IMAP::Simple provides a simple way to access and manipulate information
 on Internet Message Access Protocol (IMAP) capable servers. The API is mostly
 equivalent to Net::POP3, with some additional extensions based on the other
 features supported in the IMAP standard. This module supports connections via
 SSL using IO::Socket::SSL (see libio-socket-ssl-perl), over IPv6 using
 IO::Socket::INET6 (see libio-socket-inet6-perl) and handling messages in
 various ways (delete or undelete, mark as read or unread, expunge, edit
 flags, and more).
