This is a message for My Web Minder hosting customers that are using the mailbox feature of their accounts.

A security update is taking place right now on all mail servers to help prevent non-legitimate accounts (spammers) from using these servers. It started yesterday and will continue all of the week until next weekend.

The default port for SMTP (simple mail transfer protocol), i.e. outgoing mail traffic is being switched off. Some mail clients already try a different port first but then settle for 25. A mail client is the software you use to send or receive email. If you only access your emails via Webmail then there’s no need to do anything.

The new port will be 587 and it has been available for a long time. Some may have already set up their mail client with 587 but I should imagine the majority will need to change.

The advice from the system administrator is to also switch to encrypted traffic for outbound mail. That means using “STARTTLS” rather than “None” as the encryption method. This is not enforced and is up to you. Depending on your mail client settings, “STARTTLS” may require you to install a certificate. Alternatively, to accept a certificate warning each time you want to send an email. Installation of the certificate is easy though and I’ve covered that below for Outlook too.

So here goes for the instructions for the most popular mail clients.
