Can I install SmartPOP2Exchange and Exchange Server Toolbox on the same server? Is there anything I need to consider?
Yes, SmartPOP2Exchange and Exchange Server Toolbox can be installed together on the same server. When doing so, you should take this into account:
Problems with direction detection
In older versions there were problems with direction detection when SmartPOP2Exchange and the Exchange Server Toolbox were installed on the same server. To fix this, a rule is now created when SmartPOP2Exchange is installed that automatically assigns a new header field (X-JamMailSource) with a value (MailGateway) to all emails. In the Exchange Server Toolbox, this header is queried under Settings | Advanced | Mail Direction, and emails with this header field and header field value are always considered Incoming.
You can adjust these values if you want, but please make sure that they are the same in both programs.
Always keep versions up to date
Please note that you must always have the latest versions of both programs installed. Otherwise it is possible that SpamAssassin or ClamAV will be updated to a version that the other program cannot use.
Spam and virus scanning in one program only
To avoid wasting time and resources unnecessarily, you should run the spam and virus scans in only one of the programs. Since SmartPOP2Exchange and Exchange Server Toolbox share an installation of ClamAV and SpamAssassin, the scanning results are identical.
You should consider the following things when deciding which of the programs to use for scans:
Advantages of scans in the Exchange Server Toolbox
The Exchange Server Toolbox offers more configuration options and more rule actions for both scans. Therefore, the scans and especially the reaction to different results can be customized in much more detail.
Advantages of scans in SmartPOP2Exchange
Since in this configuration the Exchange Server Toolbox receives the emails directly from SmartPOP2Exchange, rejecting emails in the Exchange Server Toolbox should be avoided (otherwise this will lead to errors in SmartPOP2Exchange). So it is only possible to reject emails (based on scan results) with SmartPOP2Exchange. However, you should keep in mind that the emails have already been delivered to an account, so SmartPOP2Exchange not picking them up can be legally problematic.
