Re: [afnog] [Mailer-Daemon at mantse.gh.com: Mail deliveryfailed:returning message to sender]
Hi,
I have been trying to resolve this problem for a while, but I can't even
pin-point where the problem is. Any assistance would be much appreciated.
Here is the output of "df -k" and "fstyp -v <device>". The system is a Sun
E250 running Solaris 8. "/home (/dev/md/dsk/d0 )" is where mail is stored
i.e. users mail is stored in "/home/<usename>/Maildir"
# df -k
