The CITM service presents a local IMAP interface for your email client.

Your email client should send emails through a normal SMTPS interface:

For users of Apple Mail, please see our guide on Apple Mail Setup.

If you wish to use the splintermail command line tool for controlling your account without going to splintermail.com, the first time you run it you will need to tell it your email address, with the --user option, like this:

splintermail --user you@splintermail.com add_random_alias

After entering your password, and if you choose to allow it, splintermail will and request an API token for your account so you no longer have to specify your password on your current device, meaning you can then run (without needing a password):

splintermail list_aliases

and you should see the new random alias you just added to your account.

Windows: Uninstall Splintermail from the Windows "Add or Remove Programs" tool.

Mac: Download the OSX Uninstaller from our Download Page. To run it, open the context menu by right-clicking (or control-clicking) the icon and choose "open".

Linux: Uninstall the splintermail package with your system's package manager:

For Arch Linux: pacman -R splintermail

For Debian or Ubuntu Linux: apt-get remove splintermail

For Fedora or Centos Linux: dnf remove splintermail
