Ok so this is a little trick I picked up a few years ago when I developed the first version of ECheck and I started learning the POP3 protocol. It’s come in very handy when I’m away from my email client and don’t want to receive email anywhere and fragment my mailbox by spreading it across a few machines.
Firstly, this’ll work on both Linux and Windows systems, with no exrta software needed (assuming most Linux distros come with a Telnet client by default).
It’s a pretty useful thing everyone with an email account should know ;-).
Firstly, open a command prompt, and execute the following:
telnet <your.mail.server> 110
would obviously be replaced by the address (IP or hostname) of your POP3 server.
If you connect, you should be presended with a welcome message and a “+OK” message. You then enter the following commands to log in, replacing the contents of the “” with your details:
user <your@username>
pass <password>
After which, you should be greeted by another “+OK” assuming you managed to log in. If you make a typo, just send the line with the type - you usually cannot backspace and correct mistakes. Issue the correct command again.
Now that you’re in, let’s see your messages. To see how many messages and how big each of your messages is, send the following:
list
Once again a “+OK” line should be shown, followed by a very simple list of message IDs and file sizes (in bytes). Let’s preview a message, shall we?
top <id> <lines>
The headers for message , followed by up to number of lines from the message will be spammed to your console. You can find both the “Subject:” and “From:” header lines to decipher who the message is from and what it’s about. Of course you can also read the body…
Hmm? This message is junk mail or spam? Want to delete it before it hits your inbox?
dele <id>
… will delete the message with ID . It’s important to note that the message IDs are maintained - so if you delete message 1, message 2 will not fall into 1’s place. It’ll remain 2 for the remainder of the session.
If you’ve deleted the wrong message, all it not lost. You can ‘reset’ the mailbox status to how it was when you first connected:
rset
And once you’re done mucking around, disconnect nicely:
quit
It’s also worth noting that the commands are all case-insensitive, though I’m sure the ‘correct’ way of doing it would be to use all caps for commands, the server doesn’t seem to mind either way.
Have fun…
