That is incorrect, and it is also inconsistent with the description
with the SMTPD_PROXY feature, which states that the client receives
the filter's accept/reject status BEFORE the connection ends.

The timeout limits the duration of individual READ/WRITE operations,
such as SMTP commands and replies, and blocks of DATA content.
