SMTP Error Message
Posted on 2011-02-28
I have post fix as my SMTP server. I am also running Trendmicro IMSS on the same postfix server.
I am facing problems receiving some mails from some of the outside domain. . Some times the mails comes but some of the mails are not able to be received even from the same domain.
The sender is getting the below error message<NDR>.
What could be the reason for this. Is it any thing related to my postfix or anything related to my Trendmicro IMSS or Exchange server.
