Either way, it's good that they're telling their customers before making
the change, and giving sufficient notice for them to change suppliers if
they so choose.
As long as they're not also planning to use DMARC with a reject policy,

We have had enquiries from several of our
customers in the last couple
of days regarding an email they have received from Telecom. It relates
to a change in Telecom's email service that I find interesting.
These customers use Telecom as their ISP, and have a mailbox on
Telecom's Yahoo/Xtra service but they use their own domain when sending
messages, we are their MX host and we redirect their mail to their
xtra.co.nz address. Apparently from the end of September Telecom are
going to prevent their customers from using their SMTP servers unless
the From address on outbound email is an Xtra one (or I presume a domain
that they manage).
Up until now, we have always instructed customers to use the SMTP
servers belonging to their ISP (i.e. the ISP providing their Internet
service), that advice now goes out the window and we are going to have
to work with Telecom's customers to help them setup authenticated SMTP
to our servers.
I am not impressed that Telecom are effectively going to break their
email service (for their own customers) and are relying on others (e.g.
us) to fix their customers email for them, when in my opinion, the
customers email isn't currently broken.
