Sending
You can use the Mailcast SMTP server to send emails from your domain.
Setup
Before you can send emails from your domain, you need to configure your DNS with SPF, DKIM and DMARC records.
These give Mailcast permission to send emails on your behalf of your domain.
SMTP Users
Only authenticated users can send emails through the Mailcast SMTP server. You can create users on the send page of your domain.
Each user has a username which can match with the sending alias but does not need to.
If you have a one-to-one mapping between your alias and the sending email, you can select “Send only from this alias”.
You might have a catchall alias or need an SMTP username to send from mulitiple from addresses, for that, select “Send from any alias”.
When you create a user, a password is generated for you. You cannot change the password, but you can regenerate a new one on the users page.
Email app configuration
You’ll need to configure your email app to use the Mailcast SMTP server.
You should be able to find that under a section most likely labeled accounts.
You’ll need to enter the SMTP server address, port, username and password.
The SMTP server address is smtp.mailcast.io.
The port is 587.
The username is the username you created as a full email address with your domain name.
The password is the password that was generated when you created the user.
