Create an SSL certificate with strong, 2048 bit encryption

When creating either a self signed certificate or a certificate request, Kerio MailServer uses 1024 bit encryption. You may however prefer stronger encryption, especially if you are using a signing authority such as GoDaddy, which requires 2048 bit encryption. In this case, you may use the free OpenSSL utility that is available with most Unix or Linux based systems. There is also a version of the tool available for the Windows Operating system.

Kerio MailServer and Mac OS X Snow Leopard

Apple has announced that Mac OS X Snow Leopard will be available on Friday, August 28, 2009. Kerio MailServer versions 6.7.1 and older do not fully support the desktop clients in Mac OS X Snow Leopard. Therefore, Kerio advises that all Kerio MailServer customers do not upgrade to Mac OS X Snow Leopard at this time. While Kerio does not disclose information about unreleased products, Kerio remains committed to the Mac platform and Kerio MailServer will support Mac OS X Snow Leopard in the next service release.

Amazon confirms EC2/S3 does not meet PCI guidelines

If your business requires PCI compliant hosting services because you store, transmit or process cardholder data, hosting in the cloud may not be for you.  Most cloud providers do not have the controls or processes in place to protect sensitive cardholder data or the willingness to enter into required business arrangements with merchants.  Because of this, it is impossible to meet several requirements found in current PCI standards, leaving your business at risk for heavy fines by not being compliant.

Tips & Tricks: Optimize performance of Kerio MailServer

Kerio MailServer includes log viewing directly within the administration console. This is a quick and easy way to troubleshoot problems, identify attempts to breach security, or monitor daily activity. Although these files contain only textual information, over time they can become quite large, and without any maintenance, they can degrade the performance of the server and consume valuable space on the disk. By right clicking in the window of any log event, you can choose ‘Log Settings’. In this dialog you can enable rotation based on a time range or file size. It is highly recommended to enable this option and define a maximum number of rotated files. For example, rotate the logs every month and keep at most 12 rotated files. This would preserve up to one year’s worth of log information. Kerio MailServer does not access log files that have been rotated, therefore you can move old log files to another data store if you prefer to retain these log files beyond the specified rotation settings.
