Ignoring specific detected viruses

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

1. Use Lua scripting

2. 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
}
