Hi

I have 2 emails which have tripped

Is the output from clamscan -x --debug shown below indicate the 
offending url pair triggering Heuristics.Phishing.Email.SpoofedDomain?


LibClamAV debug: Phishing: looking up in whitelist:

Seems likely;  this is exactly the kind of URL mismatch it's intended to 
trigger on.


I have yet to find a guaranteed consistent way to take these entries and 
convert them to a local whitelist entry for a local .wdb file, but some 
variation of one of these should work:


M:clicktime.symantec.com:barclays.co.uk
X:\.clicktime\.symantec\.com:www\.barclays\.co\.uk/

However, locally I've also given up on having this enabled where it's an 
absolute black/white test;  I've disabled it for the main Clam instance, 
and set up a secondary one with this test and a list of variously risky 
third-party signatures whose results are scored in SpamAssassin instead.
