Postfix VERP Howto

Postfix VERP support

Postfix versions 1.1 and later support variable envelope return path addresses on request. When VERP style delivery is requested, each recipient of a message receives a customized copy of the message, with his/her own recipient address encoded in the envelope sender address.

For example, when VERP style delivery is requested, Postfix delivers mail from "owner-listname@origin" for a recipient "user@domain", with a sender address that encodes the recipient as follows:


Thus, undeliverable mail can reveal the undeliverable recipient address without requiring the list owner to parse bounce messages.

The VERP concept was popularized by the qmail MTA and by the ezmlm mailing list manager. See for the ideas behind this concept.
