Before relaying messages through the MailChannels Outbound filter, SMTP Authentication but be configured to allow a MailChannels owned IP to deliver messages on behalf of your domains(s).
Accurate Sender Policy Framework(SPF) records must be configured in your DNS zone settings to ensure that Internet receivers will properly identify and receive your email messages.
Using WHM/cPanel? Skip the manual setup and let our plugin do this automatically. Try our MailChannels cPanel plugin!
DNS TXT Record(s)
The following records are needed for SPF to work correctly. Replace example.com with your own domain name:
v=spf1 a mx include:relay.mailchannels.net ~all
If you already have an SPF record, simply add include:relay.mailchannels.net to this entry. Make sure to add it BEFORE the “all” mechanism as “all” always matches and typically goes at the end of the SPF record.
|Including MailChannels SPF records without the `_mailchannels` subdomain record could make it easier for other users of the MailChannels platform to impersonate mail from your domain. See Domain Lockdown for more details.
Note: DKIM keys can be correctly added for Cpanel using our Cpanel - DKIM Configuration Guide.
