This blog is about how to delete email using Telnet.
Removing mail from a server can be an issue sometimes. Perhaps you have an inbox which contains a large email you would rather not have, and is causing a download problem? Sometimes people will try and send large email attachments, rather than using technologies such as dropbox. Other times when using a slow internet connection chunky emails can cause an issue for email client applications. A typically scenario is being on the road using a slow mobile data connection.
Instead of downloading the email via your email client, you can opt to remove the mail from your server via telnet. This is an alternative if you do not have access to webmail, else would rather not give a third-party online service access to your account details. Telnet is essentially a terminal connection, which in current times can be easily accessed via Apple Mac, Windows and Linux computers using a telnet client. This guide on how to permanently delete specific mail from your server is suitable for both linux and Microsoft Windows users. So if you are using a linux distribution such as Fedora, Ubuntu etc or a Microsoft Windows operating system such as 2000, XP, Vista or 7, this support page is perfect for you.
