I'm not sure what you mean by "signature types".  Could you explain?
Are you referring to the truncated HMAC?

By the way, your outbound SMTP server 213.180.147.167 has a rather
poor reputation.  We've been running the Reputation Reporting Protocol
with several hundred sensors for a few months now and we keep a window
of 45 days' worth of events (about 1.6 x 10^9 events in total;
~400/second).  Here's the score for 213.180.147.167:

$ canit-reputation-check 213.180.147.167
213.180.147.167: smtpout7.poczta.onet.pl
        gl=142 ug=33 hs=21 hh=2 as=15177 ah=87 vr=17209 ir=13022 activity=6.1

That means 142 greylisting events, 33 ungreylisting events, 21 messages
hand-voted as spam, 2 hand-voted as non-spam, 15177 auto-detected as spam,
87 auto-detected as non-spam, 17209 valid RCPT commands and 13022
invalid RCPT commands.  activity=6.1 is a log-scale measure of how much
activity our sensors have picked up; 213.180.147.167 is a fairly active
SMTP client.

You need to get your ISP to clean up its act. :-)

Regards,

David.
