SMTP COMMANDERR sending IP mail?

» close window

The Question is:

 
I am attempting to send mail to the internet via smtp and it is returned unsent
 with the message:
 
---- Transcript of session follows ----
501  %TCPIP-E-SMTP_COMMANDERR, SMTP command error uslinear.com
 
(uslinear.com or whatever address I use)
 
This message is recieved for any address I attempt to send to. I can ping the
 addresses and IP's with no problem.
 
The SMTP server que is idle:
Generic server queue TCPIP$SMTP_GORT_00
  /GENERIC=(TCPIP$SMTP_GORT_01) /OWNER=[SYSTEM] /PROTECTION=(S:M,O:D,G:R,W:S)
  /SCHEDULE=(NOSIZE)

The Answer is :

 
  Unfortunately, there is insufficient detail here for an answer.
 
  Define the logical name
 
    DEFINE/SYSTEM/EXECUTIVE tcpip$smtp_log_level 5
 
  And restart SMTP.  This will provide you with a log of the SMTP
  symbiont activities, and potentially with clues to the problem
  reported.  Deassign the logical name and restart SMTP when done.
 
  From the log file, you might find a 501-related response such as:
 
recv buf=501 <user@host>... Sender domain must exist
 
  Which would imply anti-spam features have been enabled.  Use nslookup
  or similar, and check for anti-spam relay settings.  (Depending on
  the particular firewall configuration, you might be able to use the
  SMTP substitute domain mechanism (SET CONFIG SMTP/SUBSTITUTE_DOMAIN).)
 
  Please apply the available ECO for V5.0A or move to V5.1 with ECO,
  and try your tests again, and check the log.  If the problem persists,
  please contact the Compaq customer support center directly.  Expect
  to be asked details of the ECO status and the log file.
