Why does Claws Mail tell me that a gpg signature has expired?
The sender used a key with a time limit, you have to update your keyring regularly to receive the updated signatures, e.g. like this: gpg –refresh-keys Note: Most keyservers have problems syncing OpenPGP type keys (see http://keyserver.kjsl.com/~jharris/keyserver.html). It is recommended to switch to SKS keyservers, e.g. subkeys.pgp.net or sks.keyserver.penguin.de .
