Sendmail need to block incoming mails

Ganesan R — Tue, 21 Aug 2007 05:23:08 GMT

Hi Freinds,

I need to block incoming mail for a particular user where that user can send only outgoing mails. We are using sendmail 8.9.3 with PHNE_35950. The steps I performed are below.
1.Using /usr/newconfig/etc/mail/cf/cf/gen_cf script, created new sendmail.cf.gen file and copied to /etc/mail/sendmail.cf to enable
the blocklist recipients feature.

2. Then I create the /etc/mail/access file manually and put the below entry.
# more /etc/mail/access
test@abc.com REJECT

3.Then I created database map using the below command
#makemap dbm /etc/mail/access < /etc/mail/access

4.Restarted the sendmail daemon.

But still the user "test" is receiving mail if i send test mail from root user.

# mailx test@abc.com
Subject: test mail
test mail
.
EOT
#

Your valuable advice pls..

Did you try sending a mail from another system?

Check if you have enabled FEATURE(`blacklist_recipients')dnl

The following works for me:

cd /etc/mail

vi access
...
To:refuse@mshome.net REJECT

make

ls -lrt |tail

-rw-r--r-- 1 root root 617 Aug 21 21:05 access
-rw-r----- 1 root root 12288 Aug 21 21:05 access.db

service sendmail restart

tail /var/log/maillog

Aug 21 21:51:50 router sendmail[9867]: l7LJpog9009867: ruleset=check_rcpt, arg1=, relay=pallieter.mshome.net [192.168.30.34], reject=550 5.2.1 ... Mailbox disabled for this recipient

Mayby the following could do the trick? In case the mail domain would not be properly known in DNS?

grep mshome.net /etc/hosts
...
192.168.4.31 mshome.net

Anyway thanks for all your responses.
