Subaddress or Address tags???

I need to use subaddressing / address tags for an application on my Server. Subaddressing or Address tags refers to the abiity to send email appended with extra info, eg if my email address is, I can send mail to, or and the email will be accepted, with the address tag in place so that I can use it from an application.

Does anyone know if Virtualmin supports this functionality. I know Zimbra supports them but I have been looking at Citadel and VirtualMin, as I am using Webmin already. I can’t find any info about support for address tags for either Citadel or Virtualmin.
