For normal application e-mails you can make use of the local server's email service. You should set up your DNS to allow our servers to send e-mail from your domain by adding our SPF record.
SPF record in DNS
Your SPF DNS-record should include a reference to our SPF record. This will allow receiving e-mail servers to allow e-mails from our network. An SPF record is a TXT type record, and it's contents should look something like this:
v=spf1 include:_spf.raskesider.no include:_spf.google.com ~all
||| It is important that
include:_spf.raskesider.no is added after
v=spf1 with a space, and before
-all depending on your configuration). Do not remove or change other entries unless you know what you are doing.
If you do not know how to, you can show this page to your DNS service provider.
