Hello there, I followed this guide: https://library.linode.com/email/postfi ... ph_aliases

but how would I pipe emails for a single email address to a script?

Am i right in thinking it cant be done with a virtual_alias mysql table?

Not sure if you can put "|command" on the right-hand side of a virtual alias table. But I think you can specify "someaddress" (with no domain) on the right-hand side of the virtual alias table, then put the following in /etc/aliases.

someaddress: "|/path/to/command"

At least, the documentation seems to indicate this will work.
