By default, any emails sent out from your system are sent from the 10ninety mail server, with the sender (the "From") of the email being your own staff email address. From the receiver's perspective, the email will appear as having come from yourself, even though it was actually sent from the 10ninety mail server.
Certain mail servers might, however, treat such emails as spam - they see that the mail server used to send the email differs from the domain of the "From" address.
To workaround this, you can set-up an SPF record for your domain - this lists all mail servers that are allowed to send out emails on your behalf. You need to include mail.10ninety.co.uk in that list to reduce the chances of system emails being treated as spam.
Setting up your SPF record
To set-up an SPF record for your domain, you need to add this as a TXT record to your domain:
v=spf1 a mx include:mail.10ninety.co.uk ~all
If you already have an existing SPF record, you can update the record to include mail.10ninety.co.uk (add it before any ~all entry, which should normally be at the end of the SPF record):
Please make sure that the SPF records ends in ~all and not -all.
If you have any questions about this, please contact 10ninety support.
How can I check my current SPF record?
You can check your current SPF record via online tools such as mxtoolbox:
1. Click on http://mxtoolbox.com/spf.aspx
2. Enter your domain in the text box, leave the IP blank
3. Click 'SPF Record Lookup'
4. The current value will be displayed in green underneath the searchbox
Using DKIM to help with email delivery
Another recommended way to help improve email delivery is setting up DKIM authentication on your domain. DKIM stands for DomainKeys Identified Mail, and allows the receiving email server to verify the authenticity of emails sent from your domain. This helps to prevent email 'spoofing' - someone pretending to send an email from your domain when they don't have permission to do so.
To set-up DKIM on your domain please contact us at email@example.com and we will send over the DNS records that you need to add to your domain.
