mail.mydomain.de
(mydomain.de is
to be replaced)
Indicates how the mail
server can be reached.
@
TXT
v=spf1 mx a include:_spf.webhosting.systems ~all
SPF — allows emails to be sent from
the server specified in the A record
and in the MX record, as well as from
our mail relay. This makes it possible for
third parties to recognize whether the
email actually comes from the domain owner.
key1._domainkey
CNAME
key1._domainkey.webhosting.systems
DKIM – adds a digital
signature to ensure that
emails have not been altered
and come from the rightful sender.
key2._domainkey
CNAME
key2._domainkey.webhosting.systems
DKIM – adds a digital
signature to ensure that
emails have not been altered
and come from the rightful sender.
Both DKIM records (key1 and key2) are required for complete security.
Note that the records will only work as intended if the default DNS settings are used and emails are sent exclusively via the product's mail server. Emails sent via alternative methods such as the web server (e.g., phpmail or sendmail) or an external mail server are excluded and not valid.
