Hi, Thanks for replying. My bad, I realised I posted the log message from /var/log/message. It's quite similar to what I get in postfix log too. Here's the postfix /var/log/mailog version of a test mail that I just sent, hope this is better (also there are no other warning/panic errors before this). :)
