Your message could not be sent
It seems an exception happened when processing the message.
This is probably a javascript problem that is not related to the actual content of your message, rather the script is broken. OTOH, It might be a browser issue.
If you want to leave me a super secret message, please use this form.
The message will be encrypted in the browser using my gpg key with openpgp and send via the receiver page to my email address. The pgp javascript implementation is from openpgpjs.org and the mail sending script is from encrypt.to.
The message can only decrypted with an additional secret on my local machine (most importantly the php server or the mail servers cannot read the message). The page is using https.
Please note that the subject of the mail is not encrypted, so please do not put your secret into the subject.
If you want a reply, please include some form of messaging contact in the message itself (gtalk, email, twitter, whatever) and if you want to receive an encrypted reply, please include your key or your key id with the message.
