long SPF txt record

[Lawrence K. Chen, P.Eng.]

3.1.3. Multiple Strings in a Single DNS record

As defined in RFC 1035 sections 3.3.14 and 3.3, a single text DNS record (either TXT or SPF RR types) can be composed of more than one string. If a published record contains multiple strings, then the record MUST be treated as if those strings are concatenated together without adding spaces. For example:

IN TXT "v=spf1 .... first" "second string..."
MUST be treated as equivalent to

IN TXT "v=spf1 .... firstsecond string..."

SPF or TXT records containing multiple strings are useful in constructing records that would exceed the 255-byte maximum length of a string within a single TXT or SPF RR record.
