If the sender has software that can do RSA, yes. If their software can't do
RSA (for example, suppose they had an NAI/PGP freeware version), then the
sender cannot encrypt to the recipient.
Any OpenPGP-compliant version, though will be able to verify DSA sigs and
encrypt to Elgamal keys.
Does that answer your question? Really your question is an implementation
question, not a standards question.
