iPhone (POP)
Please note: When sending mail from a third-party mail client, your copy of the message will be saved in your Sent folder as encrypted, even if the message is sent as non-encrypted. By default, any mail sent via SMTP from a third-party mail program will be sent as non-encrypted, unless the recipient is a Hushmail customer or has previously set a passphrase for receiving encrypted email.
