You can find a quick introduction to the Identities page in the Getting Started section.
This page allows you to create one or more Identities, i.e. combinations of name, email address and other settings. For example, you can create one identity for business communication and one for personal communication. If you have more than one email address, you can create one identity per address. You will then be able to select an identity on a per-message basis.
The page consists of a list of identities and buttons to manage them. The identities list will always show at least one identity, which is then the Default identity.
To add a new identity to the identity list, click on the Add... button. The New identity dialog will then appear.
The New Identity Dialog
You have to enter the name of the new identity into the New Identity edit field. This will be the name shown in the identity list. You can choose how the new identity should be initialized by checking one of the three radio buttons in the middle of the dialog: With empty fields All fields of the new identity are cleared or preset with standard values. Use System Settings values Uses the values from Account Details → Password & User Account in the System Settings category Common Appearance and Behavior. Duplicate existing identity Copies all fields from an existing identity. You can choose which identity to copy from by selecting the corresponding entry in the Existing identities drop down box.
The General tab allows you to specify some basic settings for the currently selected identity. Your name Enter your full name here (sometimes also called display name). Although this field is not strictly mandatory, it is recommended to enter the correct value here. Organization Enter your organization here. This field is optional. Email address Enter your email address here, i.e. something like [email protected] Example 4.1. Email address So if your address is Joe User <[email protected]>, you should enter Joe User into the Your name field and [email protected] into the Email address field.
Email aliases This field contains alias addresses that should also be considered as belonging to this identity (as opposed to representing a different identity). Example 4.2. Email aliases Primary address: [email protected] Aliases: [email protected] and [email protected]
The Cryptography tab allows you to specify OpenPGP and S/MIME keys associated with this identity, as well as choosing the preferred (cryptographic) message format to use.
- OpenPGP signing key
Here you can select the key to be used when OpenPGP-signing messages written with this identity in effect. For brevity, only the short key id of selected keys is shown. Hovering with the mouse over the key list will show more information in a tooltip. To clear the label press the Clear button. To change the selected key, press the Change... button. A dialog listing all secret OpenPGP keys will be shown allowing you to select the one to use.
- OpenPGP encryption key
Here you can select the key to OpenPGP-encrypt messages to when this identity and When encrypting emails, always also encrypt to the certificate of my own identity are in effect. This key is also used for the Attach → Attach My Public Key function of the Composer. To change the selected key, press the Change... button. A dialog listing all OpenPGP keys found in your keyring will be shown allowing you to select the one to use. You can clear the list of keys and get more information about them in the same way as described for OpenPGP signing key .
- S/MIME signing certificate
Here you can select the certificate to be used when S/MIME-signing messages written with this identity in effect. To change the selected certificate, press the Change... button. A dialog listing all secret S/MIME signing certificates will be shown allowing you to select the one to use. You can clear the list of certificates and get more information about them in the same way as described for OpenPGP signing key . S/MIME encryption certificate Here you can select the certificate to S/MIME-encrypt messages when this identity and When encrypting emails, always also encrypt to the certificate of my own identity are in effect. To change the selected certificate, press the Change... button. A dialog listing all S/MIME encryption certificates found in your local keybox will be shown allowing you to select the one to use. You can clear the list of certificates and get more information about them in the same way as described for OpenPGP signing key .
Here you can choose which cryptographic message format to use by default with this identity. You can either select any of the four formats supported by KMail or leave the option at the recommended default setting of Any, which will choose a suitable format based on the recipients of the message, or might even go so far as to create two copies of the message, one S/MIME signed and/or encrypted, the other OpenPGP signed and/or encrypted.
The Advanced tab allows you to specify some rarely used or otherwise specialized settings for the currently selected identity. Reply-To address Enter the address to which replies to your messages should be sent. Only fill out this field if it is different from your normal address (specified using the Name and Email Address on the General tab), since replies default to the sender's address anyway.
BCC addresses Optionally enter addresses separated by a comma to which blind copies of your messages should be sent to. When you compose a message with this identity, the BCC field is filled with these addresses. If you want to send a BCC regardless of this setting, you should look at the Headers tab of the Composer page. Dictionary Select the default dictionary for current identity. Sent-mail folder Select the folder into which messages should be filed after sending when using this identity. IMAP users should consider changing this to an IMAP folder, so their sent-mail is stored on a server instead of being stored in a local folder. This way they can access these messages from a different location.
Drafts folder Select the folder into which drafts should be filed when using this identity. IMAP users should consider changing this to an IMAP folder, so their drafts are stored on a server instead of being stored in a local folder. This way they can easily continue to work on their drafts at a different location. Outgoing Account Select or enter an alternative SMTP server to be used when sending messages using this identity.
Here you can create and manage templates to use when composing new messages, replies or forwarded messages. The message templates support substitution commands, either simply type them or select them from the Insert Command menu. Templates specified here are identity-specific. They override global templates, but can be overridden by per-folder templates if they are specified.
This tab allows you to specify a signature (sometimes called “footer” or “disclaimer”) to be appended to each message sent using this identity.
Check the Enable signature option if you want to be able to append the signature when using this identity. To automatically append it to every new message you also have to select Automatically insert signature in the Composer configuration page. KMail can obtain the signature text from various sources. The traditional way on Unix is to read the text from a file called .signature in your home folder. This file can be shared between several programs, so you get the same signature in each mail program you use. To read the signature from a text file you select Obtain signature text from->File. Enter the filename in the Specify file edit field or click the button to the right of it to browse your filesystem. If you want to edit the file, click the Edit File button. KMail can also read the signature text from the output of a command. Thus, you can use programs such as fortune to create a new signature text for every message. Everything the program prints onto stdout is caught and used as the signature text. To read the text from the output of a command you select Output of Command. Enter the command (preferably with full path) in the Specify command edit field. As a third option, you can enter the signature text directly in KMail's configuration dialog. To do this, select Input Field Below and enter the text into the resultant text box.
KMail can send a small (48x48 pixels), low-quality, monochrome picture with every message. For example, this could be a picture of you or a glyph. It is shown in the recipient's mail client (if supported). Send picture with every message Check this box if you want KMail to add a so-called X-Face header to messages written with this identity. An X-Face is a small (48x48 pixels) black and white image that some mail clients are able to display. External Source Select File Use this to select an image file to create the picture from. The image should be of high contrast and nearly quadratic shape. A light background helps improve the result. Set From Address Book You can use a scaled-down version of the picture you have set in your address book entry. Input Field Below Use this field to enter an arbitrary X-Face string.
