mpop binary package in Ubuntu Jammy s390x

 mpop is a fast and simple fetchmail replacement to retrieve mail from POP3
 servers. Its main features are header based mail filtering, multiple
 authentication methods, TLS encrypted connections or delivery.
 .
 There are a few things mpop can do that fetchmail can't or that it
 does better:
  - mpop never ever tries to parse mail information except for the
    envelope-from address, which is the bare minimum that it has to do.
  - mpop never ever alters mail messages except for adding a "Received"
    header, which is the bare minimum that it has to do.
  - mpop uses several techniques (including pipelining) to reduce the
    POP3 protocol overhead. It is therefore much faster than fetchmail.
  - By default, mpop stores the mail UIDs (unique ids) in one file per
    account. You can poll different mail accounts in parallel.
  - The progress output is nicer ;-)
  - You can pipe the headers of a mail through a filter that decides if
    the mail should be downloaded, skipped, or deleted. This allows one
    to delete junk mail from a POP3 server without downloading the
    entire message.
  - mpop can deliver mails directly to mbox and maildir mail folders.
