The display autosizes to display disposition results for as many plugins as are emitting logs. The 3 char abbreviations are listed with their full plugin names in plugins/registry.txt. The GeoIP, p0f, HELO, FROM, and RCPT fields are compressed to fit on a typical display. If you have a wider display, use the -l option to display longer lines and more detail.
Starting from left to right, in the first block, the results are interpreted as follows:
geo - We see 2 connections from N. America, 3 from S. America, and 3 from Europe.
p0f - One system is running FreeBSD and the rest are running Windows 7.
krm - 3 of the connections will be rejected because of bad karma (sender history)
dbl - 7 are from IPs on DNS blacklists, an offense worth rejecting for.
rly - None of the IPs have relay permission.
dns - Only three senders have Forward Confirmed Reverse DNS
ear - two connections skipped testing (good karma), and the rest passed
hlo - three of the senders failed to present valid HELO hostnames
tls - one sender negotiated TLS
bmf - none of the senders presented a from address in our badmailfrom list
rbl - none of the sender domains are in a RHS blocking list
rfh - resolvable_from_host: all the sender domains resolve
spf - all but two connections fail SPF, meaning they are forging the envelope sender identity
bto - badmailto: none of the recipients are in our badmailto list
qmd - qmail_deliverable: the recipients are valid addresses on our system
rok - the recipient domain is on our system
tim - the number of seconds the connection was active
In the second block, we have two messages that were ultimately delivered.
bog - no messages were bogus bounces
hdr - the messages had valid headers
dky - the messages were not DomainKeys signed
dkm - two messages were DKIM signed and passed validation
dmc - the message from amazon.com passed DMARC validation
spm - spamassassin, one skipped processing, one passed
dsp - dspam, one skipped, one passed
clm - clamav, one skipped, one passed
qqm - qmail queue, two messages were delivered
In the first block of entries, not a single connection made it past the DATA phase of the SMTP conversation, where the content tests kick in. Other interesting observations are that many connections purport to be from Google. Ah, you say, but does Google have Windows mail servers in Estonia? If we look over to the SPF column, the lower case x is telling us that it failed SPF tests, meaning Google has explicitely told us that IP is not theirs. Instead of rejecting immediately, the SPF plugin deferred the rejection to B<naughty> to disconnect later.
