Sendmail

Sendmail is very often a security risk. Therefore it is very important that you be running the newest version or at least a fully patched version. Also since most machines only need to send out mail to a relay host, many of sendmail functionalities can be disabled. You can download the latest version of sendmail forhttp://www.sendmail.org.

1. ____ replace the existing /etc/mail/sendmail.cf [14] with the following

# Minimal client sendmail.cf

### Define macros

# define the mail hub – Put hostname for local site here.

DRmailhost

# define version

V8

# my name for error messages

DnMAILER-DAEMON

# UNIX initial From header format

DlFrom $g $d

# delimiter (operator) characters (old $o macro)

Do.:%@!^/[]+

#From of the sender’s address

Dq<$g>

# queue directory

OQ/var/spool/mqueue

### Mailer Delivery Agents

#Mailer to forward mail to the hub machine

Mhub, P=[IPC], S=0, R=0, F=mDFMuCX, A=IPC $h

#Sendmail requires these, but they are not used

Mlocal, P=/dev/null, F=rlsDFMmnuP, S=0, R=0,A=/dev/null

Mprog, P=/dev/null, F=lsDFMeuP, S=0, R=0 A=dev/null

### Rule sets

S0

R@S+ $ #error $: Missing user

R$+ $ #hub $@$R $:$1 forward to hub

S3

R$*<>$* $n handle <> error address

R$*<$$*>$* $2 basic RFC822 parsing

Since you have removed sendmail from the startup scripts you should schedule a cronjob to run sendmail every hour so any mail can be processed.

1. ____ crontab -e
2. ____ add the following lines

## run send mail once an hour

* 0 0 0 0 /usr/sbin/sendmail –q
