[courier-users] Courier and rfc 4408 spf

Tue, 04 Nov 2014 03:10:49 -0800

Hi,
 
The problem occurs when the domain is in your SPF record on multiple lines for the TXT record.

Domain: algartelecom.com.br

TXT record:

         "v = spf1 ip4: 189.112.116.20 ip4: 200.170.137.98 ip4: 200 170 169 128 ip4: 20
0.225.197.0/24 ip4: 200 225 223 133 ip4: 201.16.216.25 ip4: 201.48.140.94 "
         "include: 17386.meuspf.com include: 21316.meuspf.com include: spf.protectio
n.outlook.com include: spf.virtualtarget.com.br a mx -all "

Error courier:

Nov 3 12:38:07 mail courieresmtpd: error, relay = :: ffff: 65.55.169.54, from = <marc...@algartelecom.com.br>: 517 SPF neutral marc...@algartelecom.com.br: Address does not pass the Sender Policy Framework

3.1.3. Multiple Strings in a Single DNS record



   As defined in [RFC1035] 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.


How to fix this error?


Thanks
