Dear Canvin.Hu,<br>
<br>
This email is being sent to you because it would appear that your MDaemon server has not been protected by the MDaemon AntiVirus plug-in.<br>
<br>
If you are attempting to protect your users' email by running a third party anti-virus application on your mailserver, you should be aware that anti-virus applications which are not specifically designed to operate with your email server will result in unforseen problems and degraded performance due to the way they attempt to inter-operate with the email traffic and/or files in use.<br>
<br>
MDaemon AntiVirus has been designed by the authors of MDaemon itself to specifically operate with MDaemon at just the right point in the sending/receiving process and is a vital, low cost addition to your server that will provide reliable, up to date virus protection for your email users without impacting the reliability or performance of your server.<br>
<br>
Key features of MDaemon AntiVirus are:<br>
<br>
* No hassle installation<br>
* Low costs per user<br>
* Powered by Kaspersky Labs' leading AV engine and signatures<br>
* Automated updating<br>
* Facility to subscribe to automated emergency update alerts<br>
* Multiple notification options (sender, recipient, administrator)<br>
* Designed to interact with MDaemon's own operations correctly<br>
<br>
MDaemon AntiVirus is available as a fully functional 30 day trial. Use MDaemon's Security|AntiVirus menu selection to download and install it now.<br>
<br>
Important Notes:<br>
----------------<br>
<br>
If you still need to run another anti-virus product on your server, you MUST ensure that the MDaemon folder tree is excluded from any real time scanning and that any POP3/SMTP mail stream scanning is disabled - either of these option is highly likely to break your email server.<br>
<br>
We still highly recommend that you use up to date client anti-virus applications on your users' workstation PCs as an additional method of protection.<br>
<br>
Thanks for using MDaemon!<br>
<br>
Regards,<br>
<br>
