mails with valid SPF sender don't get marked SPF_PASS

[L.P.H. van Belle]

If you setup the cachening DNS, you could add in resolv.conf 
 
options timeout:2
options attempts:2
options edns0

And is TCP and UDP allowed on port 53. 
 
Last, SpamAssassin includes a default set of 13 servers, among which 3 are picked randomly.
If you have a strickt firewall, these are probely blocked ..
 
Somethings to checkout.

Peter,



I run my own DNS servers as well. 


It looks like there is a problem in the spamassassin code when the "envelope_sender_header" is set in the configuration file.



I will report it in the upcoming hours as a spamassassin bug in the spamassassin bugzilla







Met vriendelijke groet, Best regards,

I run my own DNS servers, but requests to Google's DNS at 8.8.8.8 and 
8.8.4.4 are answered in well under a second.

$ time host www.mailscanner.info
www.mailscanner.info is an alias for foo.mailborder.com.
foo.mailborder.com has address 52.2.4.15

real    0m0.123s
user    0m0.005s
sys     0m0.000s
