ClamAV does no longer update its signatures. Even starting freshclam.exe manually fails.

One source which may cause this problem are the ClamAV mirror servers. To solve the problem, please delete the following file:

C:\ProgramData\JAM Software\ClamAV\mirrors.dat

Can I install the administration interface of the Exchange Server Toolbox on any client in the network, or just on the Exchange Server machine?

Sorry, the administration interface will work only on the Exchange Server machine.

The spam report contains:


"URIBL_BLOCKED ADMINISTRATOR NOTICE: The query to URIBL was blocked."

URIBL provides public lookups over DNS for low volume usage. If you spam check a large amount of email, or you use a shared DNS platform for resolution, you may receive a response saying the query was refused. That said, Public DNS providers such as OpenDNS or Google Public DNS are effected due to the high volume of queries they generate, as are many other internet service providers (ISP) that use caching nameservers for their customer base. 
To guarantee full functionality of SpamAssassin, forwarding should be implemented for the following domains:
- http://dnswl.org 
- http://uribl.com

I installed the ExchangeServerToolbox demo and have been pretty impressed so far. One question: I get an error when I set mail to be backed up or copied to a folder. The error shows up in the event log as "System.IO.DirectoryNotFoundException: Could not find a part of the path 'Z:\mail\High Filter\2008-02-06 '. "How can I get around this?

If your drive Z: is a mapped network drive you may enter the UNC path instead (\machine\mail\HighFilter) in the backup options.

Is it possible to alter the standard SpamAssassin rules? So i can weigh a rule with less, or more points.Is there a way to update SpamAssassin or ClamAV, or is this happening automatically?

Yes, you can adjust the SpamAssassin rules as you like.
You can use the build in custom SpamAssassin config file editor which you can find under Spam Options to create a .cf-file suited to your needs.For further references see:
http://wiki.apache.org/spamassassin/WritingRules
https://spamassassin.apache.org/full/3.4.x/doc/Mail_SpamAssassin_Conf.htmlAlternatively you can create a .cf-file manually and store it together with all the other .cf-files.
We recommend to use the letter "X" as prefix for the name of your CF-file (like"XMyRules.cf").
SpamAssassin as well as ClamAVdoes already update its rules / virus signatures every 3 hours automatically.

How can I update ClamAV myself?

You may update the dlls and exe files (C:\Programs\Common Files\JAM Software\ClamAV) of ClamAV your self by getting them from the ClamWin (http://www.clamwin.com/ ) project. But we do not give any support for this. It may cause no virus to be detected or any mail/file be detected as virus. We once had this situation when ClamWin changed some interfaces which did not result in error, just in such a strange behavior.
Hint: The virus signature files used by ClamAV are updated automatically at least every 3 hours.

Can I create my own SpamAssassin rules, and where can I store them?

Yes, you can use the build in custom SpamAssassin config file editor which you can find under Spam Options to create a .cf-file suited to your needs.
For further references see:
http://wiki.apache.org/spamassassin/WritingRules
https://spamassassin.apache.org/full/3.4.x/doc/Mail_SpamAssassin_Conf.html
Alternatively you can create a .cf-file manually and store it together with all the other .cf-files. Because SpamAssassinprocesses the .cf-files in alphabetical order, you should call your own.cf-file in a way, that it will be processed last (e.g. use x, y, z as firstletter of your file¬ís name : XMySettings.cf).

We've tested successfully the trial version of the Exchange Server Toolbox and want to license your product. Do I have to order and to install a full version (will my settings be kept ?) or can I unlock my already installed trial version to a full version?

Please order the full version through our online shop. If you overwrite your trial version with the full version, your made settings will be kept. This procedure applies as well, if you want to install upgrades of your software.

Is it possible to install this toolbox without the AV?

No.
Because the integrated ClamAV will only be installed as a service and will not be registered in any other way in the system when installing the ExchangeServer Toolbox or SmartPOP2Exchange. So it is not necessary to avoid installing it. If you don 't like to use the integrated ClamAV just turn off the option/rule and the service will be disabled. You may also use ClamAV additionally to your installed AV.

Is there anyway I can get the documentation for your products to assess their capabilities without installing them?

All our products to have their manual online. Like the one for the Exchange Server Toolbox: Online manual
SmartPOP2Exchange: Online manual
and so on....

I installed and noticed that some of the emails are not getting tagged with "SPAM " in the subject. I did not turn off Intelligent Message Filter on Exchange. Should I turn off Intelligent Message Filter?
Also, what is the best way to a .eml back to the recipient if it is a false positive email? If I send it again it gets caught by the spam filter again.

The ExchangeServer Toolbox "works before" the IMF. So if you like to use IMF together with the Exchange Server Toolbox it 's ok. The SpamAssassin used by the Exchange Server Toolbox adds mail headers to every scanned mail and the spam report to the event log . So if you have false positives you should have a look at the mail header or in the log of the Exchange Server Toolbox which SpamAssassin spam rules matched on that mail and should train the bayes filter. Eml files from the backup can easily be "send" to the Exchange Server again by using the Exchange Server Pickup folder. Where you can find the pickup folder depends on the Exchange Server version you use and its configuration.See: Microsoft Technet

Can I set my own scores for Spam recognition?

Yes, you can. Place your own score best in local.cf, so they will overwritethe default values.
