manual formating of Received: hdrs; changed hdr for local receival Now the Received: headers are much friendlier to read. About folding: We must fold any line at 998 chars before transfer. We should fold the lines we produce at 78 chars. That is what RFC 2821 requests. We should think about it, somewhen. The header for locally (i.e. non-SMTP) received mail is changed to the format postfix uses. This matches RFC 2821 better. The `from' clause should contain a domain or IP, not a user name. Also, the `with' clause should contain a registered standard protocol name, which ``local'' is not.
