-In some cases a virus scanner may incorrectly detect files as being viruses. If this happens with a VPOP3-integrated virus scanner it will prevent the incoming attachment from being received. This can especially happen if you have the virus scanner configured to detect PUAs (potentially unwanted applications).
-Starting with VPOP3 v6.17 there are a couple of ways around this problem
-  - Use [[reference:virus_scan_filter_script|Lua scripting]]
-  - Use attachment filtering
-If the advanced attachment filter rules set variables **virusfilterregexp** or **virusfilter** then VPOP3 will compare the detected virus name (not the attachment name) with the value of those variables. **virusfilterregexp** will be treated as a regular expression and **virusfilter** will be treated as a wildcard string
-An example of an advanced attachment filter could be:
-  {
-   rulename skip eicar from known sender
-   variable senderaddr text test@pscs.co.uk
-   setifmatch virusfilter set *eicar*
-  }
-or
-  {
-   rulename skip eicar from known sender
-   variable senderaddr text test@pscs.co.uk
-   setifmatch virusfilterregexp set /eicar/i
-  }
