A message that you sent could not be delivered to one or more of its
recipients. This is a permanent error. The following address(es) failed:
xxx@xxx.com.sg
unrouteable mail domain "xxxcom.sg"
wat does this means? This xxx.com.sg is a valid domain and xxxx@xxx.com.sg is a valid email but seems like I can't send mail to this address. I only have this problem when I sent out mail from my forum... no problem when I use outlook. Anyway to rectify?
by the way how to setup in a way so dat any bounce mails wun be hang in my mail queue and will bounce to my email(so I can actually know which email was bounced).
