Can't modify an existing SPF record

Hi Roberto,

You need to prefix it with “a:” to indicate that this is an A-record, i.e.:

a:relay.company.com

Best,

Richard.

Hi Roberto. What domain is this SPF for and exactly how are you trying to add the extra term?
Cheers, Greg

Dear, from my webmin interface for BIND9, I try to add an additional
allowed sender host to our SPF record, but I get the following error:

Failed to save record : 'relay.company.com<http://relay.company.com>' is not a valid host to
allow sending from

What does this mean? Do I have to consider some important thing I'm forgetting ?

relay.company.com<http://relay.company.com> is already defined in our public DNS, and it has a
reverse record too.

if I add this record by hand, it's not replicated to the DNS slaves.

Thanks in advance!!!
