Форум поддержки Thunderbird

I have imported a public key in my openpgp key-management/ In my settings of the end -to-end keys: preference of key technology: choose auto the key technology by the available keys. I have read openpgp standard supports inline en s/mime encryption but what is used by thunderbird when I choose openpgp as key encryption when i type/send an email (w/o attachment by myself). I ask it because my correspondent only decrypts inline encryption.
