One rationale given for the rule is that the offeror nominates the post office as implied agent and thus receipt of the acceptance by the post office is regarded as that of the offeree. The main effect of the posting rule is that the risk of acceptance being delivered late or lost in the post is placed upon the offeror. If the offeror is reluctant to accept this risk, he can always expressly require actual receipt as a condition before being legally bound by his offer.
