Please Whitelist This Site?

I know everyone hates ads. But please understand that I am providing premium content for free that takes hundreds of hours of time to research and write. I don't want to go to a pay-only model like some sites, but when more and more people block ads, I end up working for free. And I have a family to support, just like you. :)

If you like The TCP/IP Guide, please consider the download version. It's priced very economically and you can read all of it in a convenient format without ads.

If you want to use this site for free, I'd be grateful if you could add the site to the whitelist for Adblock. To do so, just open the Adblock menu and select "Disable on tcpipguide.com". Or go to the Tools menu and select "Adblock Plus Preferences...". Then click "Add Filter..." at the bottom, and add this string: "@@||tcpipguide.com^$document". Then just click OK.

Thanks for your understanding!

Sincerely, Charles Kozierok

IMAP Selected State: Message Manipulation Process and Commands
(Page 1 of 3)

Once the IMAP client has been authorized to access the server, it enters the Authenticated state, where it is allowed to execute tasks on whole mailboxes. Since IMAP allows multiple mailboxes to be manipulated, message-specific commands cannot be used until the client tells the server what mailbox in wants to work with. Only one mailbox can be accessed at a time in a given session.

After the SELECT or EXAMINE command is successfully issued, the session enters the Selected state. In this state, the full “palette” of message and mailbox commands is available to the client. This includes the message-specific commands below as well as the mailbox commands defined for the Authenticated state. Most of IMAP's message-specific commands do not include a mailbox name as a parameters, since the server knows automatically that the commands apply to whatever mailbox was selected in the Authenticated state.

The session remains in the Selected state for as long as the client continues to have work to do with the particular selected (or “examined”) mailbox. Three different actions can cause a transition out of the Selected state:

  • If the client has nothing more to do when it is done with the current mailbox, it can use the LOGOUT command to end the session.

  • The client can use the CLOSE command to tell the server it is done with the current mailbox but keep the session active. The server will close the mailbox and the session will go back to the Authenticated state.

  • The client can issue a new SELECT or EXAMINE command. This will implicitly close the current mailbox and then open the new one. The transition in this case is from the Selected state back to the Selected state, but with a new current mailbox.
