List-Unsubscribe and Mailto Headers

Well it looks as though the developers have included some of the envelope headers but not all are working as they ought to be. I compared the results from a 2.10.19 newsletter to that received from the newly installed 3.0.0 (& 3.0.4)

The developers though in the meantime for the v3.0.0 release have added some new options and have only partially addressed those that should have been in the v2.10 series.

In the above v3 example, the ones that I have an issue with are :-

---

Received: from

Why is this in here I do not want to display the remote IP address of my broadband hub everytime I run ProcessQueue from my workstation. I've added the removal of this as an optional hack to the download instructions. It should also be noted that too many "Received-From" headers can mark email as spam, so best to remove this one.

Resolution: Removed in the hack

---

Precedence: bulk

The developers have re-instated this option, so I've removed it from my hack.

Resolution: No Problem

---

Bounces-To:

Looks as though this replaces the Errors-To header, though you will need to modify the message-envelope in the config.php file to reflect the address that you want the bounces to go to. This one does not appear to be in any of the available RFC guidelines relating to Envelope Headers so not entirely sure where the developers got this from. It will be removed from my system until such time that it is officially recognised by the RFC.

Resolution: Removed in the hack and replaced by Errors-To:

---

List-Help: <>

Obviously not fully operational as yet. Will have to wait and see what the developers do. For now I have removed it.

Resolution: Left this one in. Works with SMTP not phpMailer ?

---

List-Unsubscribe: <>

Again not operational as all the relevant data is missing and no obvious means of editing the settings from the admin pages. See my hack to correct this.

Resolution: Removed the phpList variant and replaced with mine in the hack.

---

Reply-To:

This has been added by the developers, however it appears that the user cannot define the email address to be used..

Resolution: Removed the phpList version and re-installed my hack from v2. According to some reports this is the header to use for Bounce Handling as the Return-Path is considered flakey. Set this to the same as the Return-Path for now..

---

List-Subscribe:

This is new, so we'll leave it alone

Resolution: No Changes

---

List-Owner:

Another new option, which we will also leave as is.

Resolution: No Change

---

Errors-To:

This was replaced by the Bounces-To header by the developers, however picking up the wrong email address.

Resolution: The emailing jury is out on this one, some say yes, others no. For now it stays

---

Return Path

A lot of mail delivery systems use this when a mail is bounced but by default phpList sets this to the From Address..

Resolution: Not a major Problem, just make sure that you enter the correct email address for the message evvelope in the bounces section of the config.php file.

Download

Shown below are all the code modifications required to include the List-Unsubscribe header in your eMails based on the original phpList forum contributors work (cs & btushar).

These modifications can be added to version 3.0.2 and have been tested on my production environment on a hosted server.

As with all hacks make sure you take the necessary precautions before updating your production system..

List-Unsubscribe options appear in both gmail and hotmail, however only the gmail has so far successfully replied which is not a surprise due to the lack of speed with the other.

DO NOT

Do Not apply these modifications to phpList v2.10.19 and below.
