Web Service 361
m Sent Folder is the name of the IMAP folder where mail service puts messages after
sending them. The default is Sent Messages.
m Draft Folder is the name of the IMAP folder where mail service puts the user’s draft
messages. The default is Drafts.
You can configure these and other settings—such as which mail server provides mail service
for WebMail—by running an interactive Perl script in a Terminal window, with root privileges.
These configuration settings apply to all Web sites hosted by your Web service.
To configure basic WebMail options:
1 In the Terminal application, type
cd /opt/squirrelmail/configure
sudo ./conf.pl
2 Follow the instructions displayed in the Terminal window.
WebMail configuration changes do not require restarting Web service unless users are logged
in to WebMail.
To further customize the appearance (for example, to provide a specific appearance for each
of your Web sites), you need to know how to write PHP scripts. In addition, you need to
become familiar with the SquirrelMail plug-in architecture and write your own SquirrelMail
plug-ins.
Setting Up Secure Sockets Layer (SSL) Service
If you want to provide secure transactions on your server, such as allowing users to purchase
items from a Web site, you should set up Secure Sockets Layer (SSL) protection. SSL lets you
send encrypted, authenticated information across the Internet. If you want to allow credit
card transactions through a Web site, for example, you can protect the information that’s
passed to and from that site.
When you generate a certificate signing request (CSR), the certificate authority sends you a
certificate that you install on your server. They may also send you a CA certificate (ca.crt).
Installing this file is optional. Normally, CA certificates reside in client applications such as
Internet Explorer and allow those applications to verify that the server certificate originated
from the right authority. However, CA certificates expire or evolve, so some client
applications may not be up to date.
Generating a Certificate Signing Request (CSR) for Your Server
The CSR is a file that provides information needed to set up your server certificate.
