Dear all,

The sendmail under redhat 9 runs normally, However, recently, the root
account cannot receive email while the others do.

The following is the test and the result to the mail server, please give me
some advice, thanks

Regards,
John.


[root [at] ns mail]# telnet 10.0.0.10 25
Trying 10.0.0.10...
Connected to ns.xx-xx.com (10.0.0.10).
Escape character is '^]'.
220 ns.xx-xx.com ESMTP Sendmail 8.12.8/8.12.8; Tue, 18 Sep 2007 12:37:08

First of all you should migrate to a current Linux release. RHL9 is EOL
since years and this way it lacks important security fixes.
