To route email through SpamExperts filtering, you need to update your domain’s MX records and, if using outbound filtering, your SPF record.

Incoming Filtering (MX Records)

Replace your existing MX records with the SpamExperts global records:
TypePriorityValue
MX10mx.spamexperts.com
MX20fallbackmx.spamexperts.eu
MX30lastmx.spamexperts.net
You must remove your old MX records after adding the SpamExperts records. Spammers actively try different MX record priorities to bypass spam filters. If your original MX records remain, unfiltered email can still be delivered directly to your mail server.
After updating your MX records, ensure your mail server’s destination is correctly configured in the SpamExperts control panel under Incoming → Destinations so that filtered email is delivered to the correct server.

Region-Specific MX Records

If you have a regulatory requirement to route email through a specific geographic region, SpamExperts offers region-specific MX records (EU, US, UK, AU, CA, ZA). See the SpamExperts MX Records documentation for the full list. The global records above are recommended for maximum redundancy. SpamExperts uptime and SLA guarantees do not apply to region-specific records.

Outgoing Filtering (SPF Record)

If you are using SpamExperts outbound filtering, add the SpamExperts SPF include to your domain’s TXT record so that receiving servers recognize mail routed through SpamExperts as authorized.

If You Already Have an SPF Record

Add include:spf.antispamcloud.com between v=spf1 and your -all or ~all qualifier:
v=spf1 include:spf.antispamcloud.com include:your-existing-includes -all

If You Do Not Have an SPF Record

Create a new TXT record:
v=spf1 include:spf.antispamcloud.com -all
For full SPF configuration details, including regional-specific SPF records, see the SpamExperts SPF documentation.

Outgoing Filtering (SMTP Configuration)

Outbound filtering requires your email client or mail server to route outgoing mail through the SpamExperts SMTP servers instead of sending directly.
SettingValue
SMTP Serversmtp.antispamcloud.com
Port587 (recommended, STARTTLS)
Alternate Ports465 (SSL/TLS), 25 (not recommended)
AuthenticationRequired (TLS before SMTP AUTH)
For mail server-specific configuration (Exchange, Postfix, Exim, etc.), see the SpamExperts Outbound Filtering documentation.

Verifying Your Setup

After updating DNS, allow time for propagation. You can verify your MX records are correctly configured using the MX Verification Tool inside the SpamExperts control panel, or by checking with MXToolbox. Once MX records have propagated, check the Incoming → Logs section in the SpamExperts control panel to confirm that messages are being routed through the filter.
