Advanced settings — SSL encryption

Use Secure Connection (SSL)

By default, SSL encryption is enabled for any traffic between Kerio MailServer and

Palm Treo (on default port 443).It is recommended not to change these settings

unless necessary. It is above all not recommended to disable SSL. Unsecured con-

nections can be tapped by unauthorized persons. This measure protects your

fragile information, such as username and password. If connections are not se-

cured, unauthorized users might misuse fragile data to manipulate with the email

account as well as operate in your company’s network in case the username and

password used for these are identical.

To allow the encryption, it is required that an SSL certificate is installed on the

device. If your company uses certificates authorized by a commercial certification

authority, it is possible that your device already includes support for SSL encryp-

tion. If the company uses a certificate generated by Kerio MailServer or another

internal certificate, it is necessary to install another certificate on the device; oth-

erwise, the synchronization would not work. To get information on how to install

such certificates, contact your network administrator. In chapter

Support for

ActiveSync

, Kerio MailServer, Administrator’s Guide also provides instructions

on installation of certificates on mobile devices.

Changing port number

Under certain circumstances, parameters of your mailserver may be configured

in a way that non-standard ports are used. If the HTTP service used for the syn-

chronization is running on a non-standard port, ask you network administrator to

give you this information and specify the correct port number in the Port Number

entry.

Setting authentication against the proxy server:

In the last step of the wizard (see figure

), click on Advanced. The next step of

the wizard just opened covers the issue of SSL encryption (see above). Click on Next.

This opens a dialog covering the issue of authentication against the proxy server (see
