Blacklisting Spam domains using Sendmail

In sendmail 8.8.7 and above, you can create a deny file that will block entire domains.

/etc/mail/deny file example:

IAMASPAMMER.COM REJECT
ASP-PLATFORM.COM REJECT
SMTP.OFRSVR.COM REJECT

After creating/editing the deny file you must issue this command:
makemap hash deny
which will create a deny.db file

to create the deny.db database file which sendmail uses.

Notes on sendmail smtp authentication

There are various notes around on setting up a password protected Sendmail relay box, which allows your users on one domain to send mail via sendmail in another domain, WITHOUT allowing relaying as an anti-spam measure.

Once set up, your users SMTP mail client settings require you to set a username and password.

You need to uncomment each of them, and make a few changes. Since verizon still uses plain text authentication, we need to tell Sendmail about that. After making the changes, my section in the sendmail.cf section looks like this (note the PLAIN as part of the AuthMechanism):

Once sendmail.cf is created with SMTP AUTH, you need to edit
the default-auth-info file (or create one)

Extract from sendmail.cf:
# list of authentication mechanisms
O AuthMechanisms=PLAIN GSSAPI KERBEROS_V4 DIGEST-MD5 CRAM-MD5

# default authentication information for outgoing connections
O DefaultAuthInfo=/etc/mail/default-auth-info

# SMTP AUTH flags
O AuthOptions=A


Example default-auth-info:
username
username
password
outgoing.verizon.net

Clean Mandrake 9.1 install and Apache

If you do a fresh 9.1 install, Mandrake installs the Apache 2 webserver.

Apache 2 radically changes where it puts its config files - rather than a single httpd.conf file, the various sections are now split into multiple conf files.

I had a problem getting apache to recognise .htm files as php. Here's how I solved it.

Go to /etc/httpd/conf.d
Edit 75_mod_php.conf
Add the following line in the section.
AddType application/x-httpd-php .htm

Restart apache (apachectl restart)

The default Apache 2 config is placed in
/etc/httpd/2.0/conf
and its name is httpd2.conf
