disable gpg in mutt

[Fourhundred Thecat]

Hello,

how can I completely disable gpg integration in mutt ?

If message happens to be encrypted, I would like mutt to simply show me
the source (encrypted).

I thought, I don't have gpg configured, but when I wanted to compose new
message, this happened:

   Recall postponed message? ([yes]/no):

   Enter PGP passphrase:

   Decryption failed.

I don't know how that happened. I am using gpg on the same account, but
through Thunderbird client. I have Thunderbird set up locally on my
laptop with gpg, and I am using mutt to read messages remotely on the
server. That is why I don't want to use gpg in mutt, so that I don't
have to type my password on the remote server.

anyway,

how can I use mutt unaware of gpg ?

thanks,
