But why did you enable hashcash generation, if you don't have the binary? If you are using the same .emacs on several systems, some with a hashcash binary, and some without, it seems the proper .emacs setting would be: (setq message-generate-hashcash (executable-find "hashcash")) > The user can't override the error otherwise to send mail, and has to > manually set hashcash-path to nil. I'm not sure I agree with this view. It seems the user already overrode the default behavior when she request hashcash in the first place. So she could revert to the default behavior by disabling it: M-x set-variable RET message-generate-hashcash RET nil RET I think this is comparable to other features: User requests PGP, but PGP doesn't exist => error. User requests spell check, aspell doesn't exist => error. User attaches a file, but file doesn't exist when message is sent => error. I feel that replacing all these errors, including the hashcash one, with a warning would be confusing. But if you think your view is more user friendly, then change it. Thanks.
