Weird problem with srs-socketmapd.0.32rc3.pl

I set up the 0.32rc3 installation on multiple servers and tested them to 
be sure SRS was working and mails were getting through, especially 
forwarding through one mail server in particular (call it "tampa") which 
handles a particularly important forwarded email address. Most of the 
testing was done from my servers, which all publish and run SPF1. 
Everything was okay as of yesterday. SRS was working when "tampa" received 
mail from servers with SPF (mine) and those without SPF (yahoo.com).

Now I'm getting the old SPF broken forward problem on mail sent to the 
forwarding address on "tampa": '[sending domain] does not designate 
["tampa" IP address] as permitted sender'.

Daemon srs-socketmapd is running and there have been exactly NO 
configuration changes to sendmail since I started it after the SRS 
installation, when it *was* working.

Anybody have a pointer where I should look as to why this spontaneous 
meltdown of rewriting? Thanks.
