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

In Ubuntu imapproxyd is provided by imapproxy package.

imapproxy is:

IMAP Proxy proxies IMAP transactions between an IMAP client and an IMAP server. The general idea is that the client should never know that it is not talking to the real IMAP server while IMAP Proxy caches server connections.

IMAP Proxy was written to compensate for webmail clients that are unable to maintain persistent connections to an IMAP server. Most webmail clients need to log in to an IMAP server for nearly every single transaction. This behaviour can cause tragic performance problems on the IMAP server. IMAP Proxy tries to deal with this problem by leaving server connections open for a short time after a webmail client logs out. When the webmail client connects again, IMAP Proxy will determine if there is a cached connection available and reuse it if possible.

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

sudo apt-get -y install imapproxy

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

You can also use apt command to install imapproxy.

sudo apt -y install imapproxy

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

sudo aptitude install imapproxy
