Changes to SMTP Ports

As of 1st October 2019, any mail client sending via SMTP through our mail server should use port 587 instead of ports 25 or 465. Details on how to change this will vary on your mail client, but we've detailed some of these further down this article.

It is also advisable to use STARTTLS for your encryption method.
