Dear all,

Under redhat 9, I install the sendmail with version 8.12.8-4, It can
receive
emails from the users of the same server but cannot receive from those of
other servers. Why? Note that the service have already enabled in both the
ipop and the imap file. Please give us possible suggestion, thank.

Perhaps because sendmail was started to listen only on 127.0.0.1.

Have a look in your /etc/mail/sendmail.mc, it could be that this line needs
commenting out :

dnl # The following causes sendmail to only listen on the IPv4 loopback
address
dnl # 127.0.0.1 and not on any other network devices. Remove the loopback
dnl # address restriction to accept email from the internet or intranet.
dnl #
DAEMON_OPTIONS(`Port=smtp,Addr=127.0.0.1, Name=MTA')dnl



Once you've sorted that, you can check that sendmail is listening on all
interfaces with :

# netstat -tlp

You should see something like :

tcp 0 0 *:smtp *:* LISTEN xxxx/sendmail
