Lowercase checkbox to prevent conversion to lowercase. (This parameter corresponds to the -foption on the K configuration line in the sendmail.cf file.)

11.Click on Submit to change the server configuration.

When the Suppress Errors in the Absence of the Database Files checkbox is not checked, the Administration utility checks that the filename.dir and filename.pag files exist (where filename is the name of the virtual user table you specified in the Database File Name field).

If there are no errors, the utility displays a message confirming that the configuration has been changed, and indicates that the Sendmail server has been restarted. Click on OK to return to the Configure SMTP Server menu.

If there were any errors in the configuration, the Administration utility displays a list of the errors. Click on OK to return to the Configure Virtual Domains form.

Enabling Procmail as a Local Mailer

When you enable your Sendmail server to use /usr/bin/procmail as a local mailer, Procmail is used as a replacement for the local mailer (for example, /bin/mail, /usr/bin/mail, mail.local, rmail, and so on) to deliver to /var/spool/mail. Procmail allows system-wide mail filtering. (For more information, see the procmail(1) reference page.)

To configure your system to use Procmail as a local mailer, follow these steps:

1.Under Mail on the Manage Components menu, choose Sendmail Server.

2.From the Sendmail Server Administration menu, choose Configure Sendmail Server.

3.On the Configure Sendmail Server menu, make sure that Server is selected and click on Configure.

4.From the Configure Sendmail Server menu, choose Enable/Disable Procmail.

5.On the Enable/Disable Procmail form, if Procmail is not currently enabled, click on Enable. Otherwise, click on Disable.

The Administration utility displays a message confirming that the configuration has been changed, and indicates that the Sendmail server has been restarted. Use the navigation bar to return to the Configure SMTP Server menu.

Enabling Anti-Virus

Clam AntiVirus is an anti-virus toolkit for UNIX, designed for e-mail scanning on mail gateways. It provides a flexible and scalable multi-threaded daemon for e-mail scanning. Clam AV is licensed under the GNU General Public Licence and it is POSIX compliant, and portable. It detects viruses, worms and trojans and scans within archives and compressed files.

Amavisd-new is a high-performance interface between mailer (MTA) and content checkers: virus scanners. Amavisd-new is Perl component ensuring high reliability, portability and maintainability. Amavisd-new uses several external programs and Perl modules for its operation. If there are any security vulnerabilities in them, the entire setup could be affected.

To enable Clam AV and Amavisd-new, follow these steps:

1.Under Mail on the Manage Components menu, choose Sendmail Server.

2.From the Sendmail Server Administration menu, choose Configure Sendmail Server.

3.On the Configure Sendmail Server menu, make sure that Server is selected and click on Configure.

4.From the Configure Sendmail Server menu, choose Enable/Disable Clamav and Amavis.

5.On the Enable/Disable form, if Clamav and Amavis are not currently enabled, click on Enable. Otherwise, click on Disable.
