Dear Wietse,

So how we will resolve the issue. Please let me know for your valuable suggestion.


As your log clearly shows, the OTHER SIDE of the SMTP conversation tells you this. If this other side is a receiving SMTP *server*, then they are rejecting your message.

If, as Wietse suggested, the other side is a virus/spam gateway on YOUR side, then this gateway is broken or misconfigured in some way (since it should probably not reject your own messages.)

Regardless, it is a proper 5xx response, telling postfix to bounce the message.

Only the OTHER SIDE can shed ligt on whether or not this was in error, or in fact the desired outcome.

    Are your SMTP connections intercepted by an anti-virus system?
