You can set up an SPF (Sender Policy Framework) record to verify that Speedadmin can send outgoing email on behalf of your email server. An SPF record is a tool you can use to authorize Speedadmin to send email on your behalf.
Understanding how it works
An SPF record is a single line of text that declares which SMTP servers, other than your own, are allowed to send email as if it originated from your domain.
This is accomplished by adding a DNS (Domain Name Servers) text record. (Think of DNS as a publicly accessible record for the internet.) This record enables you to state publicly that Speedadmin is an authorized sender for your email domain.
When an email client receives a message, it usually performs an SPF check to verify that the email came from who it says it did. If there isn't a valid SPF record identifying the IP address which sent the email as a sender, some receivers might consider that email spam or a phishing attempt, and flag it as untrustworthy or not display it to your customers at all.
Speedadmin avoids this by sending email using our own domain when you authorize Speedadmin with a proper SPF record. Nevertheless, email sent from Speedadmin should never be marked as spam.

Setting up an SPF record
Ideally, this is a task you'd get help with or have your system administrator take care of, if you can.
If you've already set up an SPF record for another purpose, you can simply add a reference to Speedadmin to it. The SPF specification requires that you only have one SPF record on your domain, if you have multiple records, it may cause issues, and cause rejections of your email.
For example, instead of having two separate records, such as
v=spf1 include:_spf.google.com ~all
v=spf1 include:speedadmin.dk ~all
... you can combine them into one, like this:
v=spf1 include:_spf.google.com include:speedadmin.dk ~all.
To create or edit an SPF record to reference Speedadmin
Edit your domain's DNS settings to add a TXT record. The steps vary depending on your domain registrar.
Speedadmin recommends using the following SPF record:
v=spf1 include:speedadmin.dk ?all
While we recommend using ?all because it's the least intrusive qualifier, you can use whichever qualifier you are comfortable with.
