The issue does not concern the emails but the buffer used internally
to store the received raw data sent by client.
The user who wants to fix the issue (#1745035) should override the
collect_incoming_data method which is usually not meant to be
modified.
Moreover, there are two RFCs which state that extremely long lines
must be truncated and an error reply must be returned.
