Thanks Mark!

yes, the postfix mail log shows the mail is sent out, but i check the smtp
log & post log in mailman,it shows the mail posted by 2 days later. there is
an error message in email header:
 "Received-SPF: error (google.com: error in processing during lookup of
is it the mailman problem?

i telnet my server smtp port, it comes time out. i use mxtoolbox to test
smtp, it shows "Reverse DNS FAILED! This is a problem"

dig my server, there is only 1 query with no anser, also have a warning:

";; ->>HEADER<<- opcode: QUERY, status: REFUSED, id: 54907
;; flags: qr rd; QUERY: 1, ANSWER: 0, AUTHORITY: 0, ADDITIONAL: 0
;; WARNING: recursion requested but not available
i am a beginer with ubuntu, i really don't know how to do?

thanks all of you in advance!
