<p>There can only be one SFP TXT record per domain. A complete
record could look like.....</p>
<p>domain1.com. IN TXT "v=spf1 a:mail.domain1.com
a:smtp.domain1.com a:relay.domain2.com -all"</p>
<p>It should be logical to use a (domain) name because that name
could have multiple IP addresses, both IPv4 and IPv6.<br>
Note that there are double quotes around the whole TXT string as
well.<br>

<p class="MsoNormal">Dear, from my webmin interface for
BIND9, I try to add an additional<br>
allowed sender host to our SPF record, but I get the
following error:<br>
<br>
Failed to save record : '<a
href="http://relay.company.com" target="_blank"
moz-do-not-send="true">relay.company.com</a>' is not a
valid host to<br>
allow sending from<br>
<br>
What does this mean? Do I have to consider some important
thing I'm forgetting ?<br>
<br>
<a href="http://relay.company.com" target="_blank"
moz-do-not-send="true">relay.company.com</a> is already
defined in our public DNS, and it has a<br>
reverse record too.<br>
<br>
if I add this record by hand, it's not replicated to the
DNS slaves.<br>
<br>
Thanks in advance!!!<br>
