This is related to Qmail in RHEL-5 which I have configured from docs provided in Qmailrocks.org.I have been some problem while sending mails through telnet. When I send mail , error appears
"451 qq trouble creating files in queue (#4.3.0)"


[root@pc1 ~]# qmailctl stat

No benefit from running queue-fix.

# /var/qmail/bin/qmail-queue <msg
# echo $?
64

Which I read in some docs that 64 means Problem with queue/mess.

What should I do next ?
