Secure Sockets Layer (SSL) enables the HTTP protocol to be secured. This page will show you how to configure SSL in Apache and SquirrelMail.

Configuring Apache for SSL

Keypair generation1. Generate a certificate using the genkey tool.
Edit ssl.conf2. Edit the file /etc/httpd/conf.d/ssl.conf and edit the lines below.
DocumentRoot /usr/share/squirrelmail
ServerName mail.acme.local:443
SSLCertificateFile /etc/pki/tls/certs/mail.acme.local.cert
SSLCertificateKeyFile /etc/pki/tls/private/mail.acme.local.key
Replace mail.acme.local with your server name.
NoteIf you are using Red Hat Enterprise Linux 6 or CentOS 6, the generated certificate file will have a .crt extension instead of .cert.
NoteIf you are not using Red Hat Enterprise Linux or CentOS, make sure the lines below are present. 
LoadModule ssl_module modules/mod_ssl.so
Listen 443
Service Configuration3. Restart the httpd service. Learn how to restart services here.
HTTPS SquirrelMail4. Try accessing SquirrelMail using https instead of http.
NoteYou can force browsers to always use the SSL version. See Relocating SquirrelMail into the domain root.
