An Internet domain name (registered with us or elsewhere) needs the following DNS record to be able to make use of our email servers:

Type: MX
Host: ‹yourdomain›
Priority: 10
Points to: mail.leanservers.com

Type: MX
Host: ‹yourdomain›
Priority: 20
Points to: mail2.leanservers.com

Please keep in mind that it will take up to 24-48 hours from the moment you create the DNS record until the service is fully functional since the information needs to be propagated worldwide.

Additionally you may want to set up the SPF record as follows:

Type: TXT
Host: ‹yourdomain›
Value: v=spf1 a mx include:leanservers.com ?all

Finally, if you want to activate Domain Keys you will need the following DNS records:

Type: TXT
Host: private._domainkey.‹yourdomain›
Value: k=rsa; p=‹string_provided_by_Leanservers_support›

Type: TXT
Host: _domainkey.‹yourdomain›
Value: o=-
