--- Comment #5 from William Herrin <herrin-spamassas...@dirtside.com> --- tcpdumping on my mail server, I see a UDP DNS request going out for TXT overdrive.com, a UDP response returning with the truncated flag and no followup TCP attempt. Trying with "dig" shows the UDP request, truncated response and then TCP request and response. It appears that the SPF module is not falling back to TCP on my machine. -- You are receiving this mail because: You are the assignee for the bug.
