EmailTrends newsletter 05/23

I’ve been thinking about it for some time:
the old directions to “block” inactive domains via the TXT record: “v=spf1 -all” no longer work.
Now it’s all up to the _dmarc record. Below is a brief explanation, a little technical.

Until a few years ago it was sufficient to declare that there was no smtp server authorized to send for a domain,
to have messages sent without authorization from that sending domain treated as “SPAM” or rejected.

Today we need to add a new “_dmarc” record to the domain’s dns,
to warn recipients that they should only accept messages authenticated with SPF and/or DKIM,
otherwise they will be considered as “SPAM” or rejected.

Is there an easy way to protect domains that don’t send emails from ABUSE?

Most companies and public bodies register multiple domain names.
The numbers can vary from a few dozen domains up to several hundred for a
single activity.

Many of these domains are not public or they do NOT send emails.
Misconfigured domains can easily be exploited by malicious actors.

A quick setup allows you to declare that a given domain is NOT in use,
warning recipients to reject any email from that domain.

Receiving clear and structured information via the internet can be
complicated. It needs a user interface to fill in and a server application
that sends the data.

The FormMail app lets you create simple and responsive forms
that will send the data directly to your email address.

Only a few lines from the May 2023 newsletter describe this service.

It all started with the correction of the script offered by RealSender
for sending email messages from html pages: sending via http request.

I realized that the sender’s address, the “email” field entered in the form,
and the return-path, to which any errors are sent, was not aligned.
This caused messages submitted via forms to be identified as SPAM.

After the change, the sender and return-path are identical and authenticated by RealSender,
while the email address that the user writes in the form is used as the “reply-to” address,
so that whoever receives the form can easily reply to whoever filled it out.

Then I have been looking for a simple application for composing forms,
I thought it was a useful service for our customers.
Unfortunately, most software is complex to install and manage.

Until I ran into: Bootstrap v4 Form Builder
It worked right away, even locally on the PC, directly in the browser.

Some minor changes were needed
to integrate it with RealSender’s email sending script.

The use is immediate: the data inserted in the form
are straight delivered to your inbox!
