Recently I get some messages back like: ----- Transcript of session follows ----- ... while talking to mail.sourceforge.net.:

<<< 550-Envelope sender verification failed <<< 550 rejected: Cannot route to envelope sender <ronald@elmit.com> (The envelope sender does not exist according to your mail server when it was asked): response from dns.elmit.com [61.220.121.18] after "MAIL FROM: <>" was "550 5.0.0 Access denied". This does not help fight spam effectively, breaks RFCs, and prevents you from getting bounces so we can't accept mail from you 554 5.0.0 Service unavailable
