In VPOP3 2.4 and later, you can use a piece of simple scripting to have VPOP3 generate different signatures based on the sender's email address.

Whenever a local user sends a message, VPOP3 tries to load a file 'signature.lua' in the VPOP3 directory. This file should contain a short program in the Lua programming language.

VPOP3 calls a function in the signature.lua file called 'GetSignature' which should have the following prototype:

GetSignature(<format>, <authenticated sender>, <sender email address>)

(where '<format>' is either "HTML" or "PLAIN")

This function should return a string which tells VPOP3 which signature to use (if there isn't a return value, VPOP3 will use the signature configured in VPOP3).

A simple example would be:

function GetSignature(Type, AuthSender, Sender)

 if string.find(Sender, "@domain1%.com$") then

  if Type == "PLAIN" then
   return "This is the signature for domain1"
  else
   return "<p>This is the HTML signature for domain1</p>"
  end

 elseif string.find(Sender, "@domain2%.com$") then

  if Type == "PLAIN" then
   return "This is the signature for domain2"
  else
   return "<p>This is the HTML signature for domain2</p>"
  end
 end
end

If you need, we can produce a script for you, but there would be a cost for this - contact support@pscs.co.uk with a specification for a quote. (The price is usually £50 + VAT for a simple case with 2 or 3 signatures which are fixed depending on the sender. If you want signatures which vary (eg contain the date/time) or more different signatures, or reading signatures from a file, then we would need to know the exact specification to be able to give you a quote.
