This page contains information on best practices for managing email in Cloud VPS.
We use the word email here as a way to refer to the several protocols involved in modern and secure email exchange (smtp, spf, dkim, dmarc, pop, imap, etc).
There are some considerations you need to take into account when planning to use these emails protocols inside Cloud VPS.
A collection of best practices.
Using Cloud VPS smtp servers
These are the smtp relay servers we have for Cloud VPS VM instances:
TODO: is this true? Can this be more detailed?
Sending emails from a Cloud VPS domain
If you send emails from a software running inside Cloud VPS, and you configure the software the use
From: address that belongs to a Cloud VPS domain (such as
wmcloud.org), make sure you are using the appropriate relay smtp server (see section above).
Not using our smtp relay servers can result in SPF errors in the destination smtp server refusing your emails.
Sending emails from a non-Cloud VPS domain
If you need to send emails from a software running inside Cloud VPS, and you need a
From: address that does not belongs to a Cloud VPS domain (such as
wmcloud.org) so people reading the email replies to a different address, this is our recommendation.
- Use a
From:address from a Cloud VPS domain, such as email@example.com. Include a
Reply-to:address in your desired external domain.
- Use CloudVPS smtp servers as relay.
