Upgrading Sendmail to 8.11.3

Obtain the latest source from sendmail.org (8.11.3 at the time of this page's creation). Put the source in a temporary place, I put it in my home directory under sendmail.

Backup your current configuration: daemon, startup script,and conf files.

   suse:~ #cp /usr/sbin/sendmail /usr/sbin/sendmail.old  (daemon)
   suse:~ #cp /etc/aliases /etc/aliases.old              (aliases file)
   suse:~ #cp /etc/aliases.db /etc/aliases.db.old        (aliases database file)
   suse:~ #cp /etc/sendmail.cf /etc/sendmail.cf.old      (configuration file)   
   suse:~ #cp /etc/sendmail.cw /etc/sendmail.cw.old      (domain aliases)
   suse:~ #cp /etc/rc.d/sendmail /etc/rc.d/sendmail.old  (startup script)

Decompress and untar the source file.

   suse:~/sendmail #gzip -cd bind-9.1.1.tar.gz | tar xvf -

Change to the newly created sendmail-8.11.3 {source} directory and read the README file

   suse:~/sendmail #cd sendmail-8.11.3
   suse:~/sendmail/sendmail-8.11.3 #less README

Configure and compile the source with the Build script.
```
   suse:~/sendmail/sendmail-8.11.3 #sh Build
```
Change to the cf/cf directory and copy the .mc file that matches your system to config.mc
```
   suse:~/sendmail/sendmail-8.11.3/cf/cf #cp generic-linux.mc config.mc
```
If you are upgrading, you can create a new sendmail.cf (step 8) or use your existing one (step 9).
Creating a new config.mc file, you can read the sendmail-8.11.3/cf/README file for options and features, these should be added before configuring the .cf file with M4 or sh Build.
1. Create the config.cf file using the m4 macro processor
```
   suse:~/sendmail/sendmail-8.11.3/cf/cf #m4 ../m4/m4.cf config.mc > config.cf
```
2. Run sh Build config.cf, it does the same thing as the above command (checks the config.* file)
```
   suse:~/sendmail/sendmail-8.11.3/cf/cf #sh Build config.cf
   using M4=/usr/bin/m4
   make: `config.cf' is up to date
```
3. Install config.cf as /etc/mail/sendmail.cf
```
   suse:~/sendmail/sendmail-8.11.3/cf/cf #cp config.cf /etc/mail/sendmail.cf
```
Using an existing /etc/mail/sendmail.cf file, lines to change in sendmail.cf:
1. Update the version of the file
```
   # level 8 config file format
   V9/Berkeley
```
2. Update the reported version, can be seen by telnet {host|IP} 25.
```
   #Configuration version number
   DZ8.11.3/Linux 8.11.3   
```
Use you startup script to stop the sendmail daemon or kill the process using ps -ax, kill -9 [sendmail pid].
```
   suse:~#/etc/rc.d/sendmail stop
```
Install the binary created in step 5, this will install the binary to /usr/sbin, and installs the man pages as well.
```
   suse:~/sendmail/sendmail-8.11.3/ #sh Build install  
```

Update the aliases.db file by running newaliases

   suse:~#newaliases
   /etc/aliases: 36 aliases, longest 10 bytes, 403 bytes total

Start the sendmail daemon.
```
   suse:~#/etc/rc.d/sendmail start
```
