 Topic: SPF and redirect keywordPosted: 21 June 2006 at 8:19am |

It seems that SPF checking with records that contain the redirect keyword doesn't work. Consistently when SF checks for gmail.com (by way of example) SPF records the following happens:
06-21-06 07:01:55:628 -- (63392) Connection from: 207.36.160.234 - Originating country : United States 06-21-06 07:01:58:222 -- (63392) found SPF record for gmail.com: v=spf1 redirect=_spf.google.com 06-21-06 07:01:58:222 -- (63392) SPF query result: unknown 06-21-06 07:01:58:222 -- (63392) - SPF analysis for gmail.com done: - unknown And no SPF check is performed. Unfortunately there are quite a few spam messages getting through with forged gmail.com addresses that could have been blocked. When I check the DNS server that our SF uses for the TXT record of _spf.google.com it works okay: > set type=txt > _spf.google.com Server: xxx.yyy.zz Address: 172.16.1.11 Non-authoritative answer: _spf.google.com text = "v=spf1 ip4:216.239.56.0/23 ip4:64.233.160.0/19 ip4:66.249.80.0/20 ip4:72.14.192.0/18 ?all" Then again, it also happens with other domains that use redirect in their SPF records: 06-21-06 13:14:10:753 -- (125396) Connection from: 212.204.245.91 - Originating country : Netherlands 06-21-06 13:14:10:800 -- (125396) found SPF record for your.hp.com: v=spf1 redirect=hp.m0.net 06-21-06 13:14:10:800 -- (125396) SPF query result: unknown 06-21-06 13:14:10:800 -- (125396) - SPF analysis for your.hp.com done: - unknown So it seems that SF doesn't process the redirect keyword correctly. Are more people experiencing this or is it just me somehow? |

No, it's not just you - I'm seeing the same thing. Here an example for gmx.ch:
06.20.06 01:17:52:884 -- (17876) Connection from: 213.165.64.21 - Originating country : Germany 06.20.06 01:17:53:337 -- (17876) found SPF record for gmx.ch: v=spf1 redirect=gmx.net 06.20.06 01:17:53:337 -- (17876) SPF query result: unknown 06.20.06 01:17:53:337 -- (17876) - SPF analysis for gmx.ch done: - unknown I'm seeing the google.com example as well. Didn't notice this before, because I wasn't looking for it, but I guess other users can confirm this quickly as well. Just do a search for 'redirect' in yesterday's log file for example. |
