I have installed GnuGPG and Enigmail and I am using PGP to digitally sign my emails. When I select digital signature I an asked for my passphrase. The email is sent with no problems but the recipient is unable to open my emails. How do I help the recipients read my emails.

Maybe you need to read the documentation for Enigmail. You encrypted the message and unless to provide the recipient a key they are not going to be able to open the message.

It rather works the other way round. The recipient needs to provide a public key to the sender, to which the sender encrypts the message.

Just signing a message does not prevent the sender from being able to read the message.

As Airmail said, reading the Enigmail documentation probably helps.

Christ1, You are correct, it is the recipients public key that I would need to encrypt an email, but digitally signing a document should not cause the email to be unreadable. You and Airmail are both correct though, I just need to go back to the manual and find out what I am doing wrong. Thank you both for the help.
