How To Fix mpopd: command not found in Ubuntu / Debian / Kali Linux / Raspbian

In Ubuntu mpopd is provided by mpop package.

mpop is:

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.

To fix this problem, we can install more using the command below.

sudo apt-get -y install mpop

This command might take some time to finish depending on your machine internet connection.

You can also use apt command to install mpop.

sudo apt -y install mpop

Or if you have aptitude installed you can use the following command.

sudo aptitude install mpop
