Website/Wizard update for BIND Long TXT records

2005-08-10 19:06:44
Another recommended update for the wizard submitted via the web site....

subject: Long SPF entries w/ BIND
message: I have run into what appears to be a BIND limitation with
long TXT records. These records are limited to 255 characters per
_line_, however, unlike TinyDNS, BIND does not automatically split
records across multiple lines automatically.

What this means is that organizations with long SPF records (e.g. when
they have many servers that can send mail on their behalf and
cannot condense the list using CIDR because the servers addresses
are not on bit-boundaries) must manually split them across multiple
lines.

Can you please make some indication of this on the SPF wizard page
(where it gives the examples of what to paste into your zone files)
and perhaps examples of how to split the records using BIND
(because this information is not readily available to the public
since it seems that TXT records do not typically grow to >255
chars).

Makes sense to me.  Is that right?
