HI,
How many character can I add in TXT SPF record? As I know the answer is 256, is this correct.
I have an issue when I create SPF record to domain xxx.com that I have 18 servers on different site use the same SMTP domain so if I create the SPF record using IPV4 format the number of character will exceed the limit.
The output of nslookup for SPF will be as two line with > symbol. With www.dnsquery.org it will be empty
Unfortunately I tried to combine IP with subnet mask without luck and we don't want to use PRT or A mechanism because we have A records for NON exchange server
Can I divide the exchange servers on two TXT file on same DNS zone?
Any Clue?
