[Pdns-users] Problem with semi-colon in TXT record

[toor]

Hi Martin,

I remember seeing this as well, as Martin said it is dig that escapes
it. If you take a look at the source for dig txt_totext() is called
which prepends \ to ;.

Easiest way to verify is to do a tcpdump when the query is run so you
can see the data that is returned by the DNS server, as an example:

14:07:07.632440 IP 192.168.1.254.53 > 192.168.1.222.34753: 30290 1/0/0
TXT "v=DKIM1;k=rsa;g=*;s=email;h=sha1;t=s;p=MFwwDQYJKoZIhvcNAQEBBQADSwAwSAJBAN3FDDsxUx9ZKq2g5dCTOs/EhZv5YRmCRkqt3YKWeyL2x1Tx+xK+8W7NWoG4V6AdLkccGJIm6jeKbX7ojlIcvL0CAwEHHQ=="
(234)

Thanks
