All fields of the new identity will be cleared, or preset with standard values.

Uses the values from your default identity.

Copies all fields from an existing identity. You may choose which identity to copy from by selecting the corresponding entry in the Existing identities drop down box.

Enter your full name here (sometimes also called display name). Although this field is not mandatory, you should enter your name here.

Enter your organization here. This field is optional.

Enter your email address here, i.e., something like joe@example.com.

This field contains alias addresses that also belong to this identity (as opposed to representing a different identity). You may define multiple aliases. To add another alias. enter an email address in the Email aliases: field, then click the + Add button

Here you may select an OpenPGP key for signing messages written with this identity in effect. For brevity, only the short key id of selected keys is shown. Hovering over the item will display more information in a tooltip. To select an existing key, use the drop down list. If you wish to create a new public / private key pair, select Generate a new key pair.

Here you may select an OpenPGP key for encrypting messages 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.

Here you may select an x.509 certificate used to sign messages written with this identity in effect. KMail cannot generate x.509 certificates. They are issued by certificate authorities. If you have added such a certificate to your key ring, KMail can import and use it.

Here you may select an x.509 certificate for encrypting messages when this identity and When encrypting emails, always also encrypt to the certificate of my own identity are in effect.

Here you can choose the default cryptographic message format to use with this identity. You may either select one of the four formats supported by KMail, or leave the option at the recommended default setting of Any; this will choose the right format for each recipient you specify, and may create multiple copies of the message, some signed and/or encrypted with an x.509 certificate, and the others signed and/or encrypted with an OpenPGP key.

Checking this box causes KMail to affix your digital signature to messages composed by this identity unless this option is manually overridden in the Composer window.

Checking this box causes KMail to encrypt messages composed by this identity whenever such encryption is possible (unless overridden in the Composer window).

Enter the address to which replies to your messages should be sent. You need this field only if it is different from your normal address (specified using the Name and Email Address fields on the General tab), since replies default to the sender's address anyway.

This field is useful if you want replies to your mail to go somewhere else than your regular email address, e.g., if you are using this identity to send messages from an email address that cannot receive replies.

Optionally enter one or more addresses, separated by commas, to which carbon copies of your messages should be sent. When you compose a message with this identity, the CC field will be filled with these addresses.

Optionally enter addresses, separated by commas, to which blind copies of your messages should be sent. When you compose a message with this identity, the BCC field will be filled with these addresses. If you want to send a BCC to the same address for every identity you define, see the Headers tab of the Composer subset (create a custom BCC header).

Select the default dictionary for the current identity.

Select the folder in which messages should be saved after sending them from 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. Then they can access sent messages from a different location.

Select the folder in which drafts should be saved 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. That way they can easily continue to work on their drafts from a different location.

Select the folder in which templates should be saved when using this identity. Please see Compose from templates for more information about templates.

Specify an alternative SMTP / sendmail® / Microsoft® Exchange server to be used when sending messages from this identity.

Choose this option if you want to attach a vCard file to each message sent from this identity. A short dialog will ensue.

Use the drop down list to select the language associated with the optional autocorrection tool when using this identity.

This field is filled with the value from the hostnames file (in /etc) by default. The Composer will append this domain name to any purely local email address you specify. This feature is primarily useful in a sendmail® environment.

These commands extract information from the message you're replying to, or forwarding, and insert that information into the composition window.

These commands will pipe the message to which you are responding through an external program, then insert the output into KMail's composition window.

These commands perform functions like choosing the dictionary the spell checker should use, or inserting the contents of a text file into the composition window.

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.

This drop down list gives you two ways to select an image.

Use this option to enter an arbitrary X-Face string. Examples are available at https://ace.home.xs4all.nl/X-Faces/
