I was looking at implementing a Learn Spam / Learn Ham feature on my
server. Basically, I’ll have a cronjob to read users’ Learn Spam
folders and use spamassassin’s learn function. Pretty basic stuff,
nothing magical going on here. SpamAssassin’s Bayesian learn function,
however, requires you teach it what ham is as well, so I want to scan
the user’s inbox for ham as well.
So here’s the trick
I want to read the seen-state db of the user’s inbox to make sure the
user has “seen” the message. The code will assume that if the user has
seen the message and has not moved it to the Learn Spam folder within a
time period (say 3 hours), then the message is Ham and learn it as such.
I modified the seenstate_db parameter in imapd.conf to use flat files to
take a look at the format of the file and got this:
7b4434cf433945c5 1 1127830200 1 1127829445 1
I don’t plan to keep it as a flat file, I was convert it back to
skiplist and use the perl CPAN module Algorithm::SkipList to read the
skiplist instead. Here’s what I make of the entry so far, but I would
like a confirmation as to what each field means:
7b4434cf433945c5 – hash of the file, but I can’t figure out what kind of
hash this is
1127830200 - last time the message was viewed
1127829445 - either first time the message was viewed –or-
the time it was entered
into the db –or-
something else ;)
As for the ‘1’s, I assume at least one of these entries has to do with
the fact it’s the 1. file in the user’s inbox, but I don’t know what the
others denote. Hence the question.
Can anyone shed light on this for me?
Look at doc/internal/database-formats.html in the Cyrus distro.
Also, if I were to use the perl module to open the seen state db quickly
to read entries, could this cause a corruption of the seen information?
It shouldn't, since Cyrus allows simultaneous access to the same mailbox
anyways, but its always safer to get this information in protocol (via IMAP)
