9.1.5. Keyserver

These are the options related to keyservers used to search public keys from.

The text field Specify your keyserver(s) allows you to specify a list of OpenPGP keyservers. These keyservers will be proposed to you next time you launch a search for a person's public key on a keyserver.
You may prepend a protocol to the name of a keyserver, e.g.
hkp://keyserver.example.com or ldap://certserver.pgp.com.

If you want, you may enter a keyserver name in the field Automatically download keys for signature verification from the following keyserver. Enigmail will then automatically try to download from the specified keyserver any public key needed to verify signed messages. If you use this option, specify only one name.
