Advanced Features

Mailtraq has a number of advanced features to manage large mailing lists, including Mailing List Address Checking and there is extensive configuration advice in the Console context Help.

Moderation

Mailing Lists can be moderated directly within the Remote Console (by approving individual messages) and it is now possible to combine address books and mail groups for mass mail transmission. 

List Maintenance

Using an address book as a target means that users can maintain the list in WebMail.  Mail Group
list membership allows everyone in a department to automatically be on a list.  Combine this feature with round-robin delivery to automatically share message amongst everyone in a sales or support department.

Per-recipient options

Per-recipient options are also available so you can have a tailored message sent to every member of a list.  As an example, just include "Dear $(name)" in the e-mail to have customised mailers. 
See Mailing-list Configuration for more.

Automatic Address Check

Address Check Messages are sent to each subscriber, with a unique return address. When a message is returned, the invalid subscriber can be automatically removed or suspended.

Strip Delivery Receipt Request

If messages with delivery receipt requests attached are received by the mailing list and are distributed unchanged to the mailing list subscribers, the mail system of each subscriber will respond by sending a message confirming receipt to the address specified in the original message. Read more in the Console context Help.

VERP - 'Bounce' processing

Mailtraq's VERP (Variable Envelope Return Path) implementation is located in the Mailing List Messages-tab marked as: Explode Messages...  VERP is designed to cope with bounces where the original subscriber address isn't included. VERP modifies the reverse path of list output messages so that it contains an encoded version of the forward path.

This option integrates the subscriber address checking facility in Mailtraq into normal mailing list traffic so that an invalid subscriber can be automatically removed or suspended. The setting entry (one in [20]) simply means that Mailtraq checks on every twentieth list input message which it receives.

Setting Explode at (one in [20]) means that 5% of list inputs are checked.
If VERP / Explode is in use and set to (one in [1]) then a mailing list to 5,000 changes from being one message to 5,000 to 5,000 individual messages.  It should be used with care because of the resource load which results from the local exploding of a single distributed list message into multiple messages, each tailored by Mailtraq to test the receiving address of an individual subscriber.
