Subject: [PATCH] Removed -(no)push and -(no)forward flags from send, spost
 and whatnow. We don't send directly (with SMTP) anymore. We
 only execute sendmail, which, on modern systems, takes few
 time. Thus we do it directly instead of having more
 complexity for the rare wish to run sendmail in the
 background and also be unable to deal with possible errors
 directly.
