it seems we need recipient pgp key for sending
encrypted email. if there is no pgp key, can i
still encrypted email?
if yes, how? i have created gpg.conf & added
auto-key-locate local,keyserver,wkd.
i am trying to end an enceyted email by adding
<#secure method=pgpmime mode=encrypt>
regards,
jindam, vani

No, not with public-key cryptography¹, which is what is usually used.
You need the recipients public key to be able to encrypt the email to
them.
If you and the recipient share a secret (eg. a password), you could use
symmetric encryption², but you have to share the secret in some other
way first, so it's rarely a solution.
Best regards,
Adam

You can't unless you use symmetric encryption (see the earlier answer
you got).
However if the Gnupg finds the key of the recipient through the
~auto-key-locate~ option you might be to find the key.
Another method would be to ask the mail provider for the public-key of
the recipient if autocrypt[1] is used. Gnus doesn't support it out of
the box however there's a third party plugin[2] that does add such support.
I haven't tested that myself.

ok. another issue resolved. since few months
k9 mail(1) is using this method.
