+One day a few years back, I wondered what mailers people were using to send me messages. So, I wrote some perl scripts to process my incoming mail and attempt to find out.
-That's something
I actually wondered one day - so I wrote some
scripts to find out
:
+I ran these
scripts for several years on my server. However, I've now switched
to hosted web space and mail (may I recommned [fastmail.fm|http
://fastmail.fm]?). Thus, I can't run my scripts any more.
-[http://www
.hollenback
.net/xmailer/all_mailers.png]
+Still, I will leave the scripts up on my web site in case anyone else wants them
. The scripts do show how to use tied databases in perl, so they might make a useful learning tool
.
-Here are the
(almost
) [raw numbers|http://www
.hollenback.net/xmailer/xmailer
-stats
.html] used to generate this graph
.
+Theory of operation: every incoming email gets fed to xmget
(via procmail
). xmget processes the message and extracts the X
-Mailer or User-Agent header
. That header is stored in a database via a tied perl hash
.
-You may notice that
the sum of all the values
in the graph does not add up to the 'total messages received' number. That is because I don't graph the number of 'unknown mailers' (messages without X-Mailer headers). You can find this number on the [raw data|http://www.hollenback.net/xmailer/xmailer-stats.html]
page. Add it to the other counts and everything will come out correct
.
+xmdump reads
the database generated by xmget and produces a pretty graph suitable for inclusion
in a web
page.
-Updated every hour (did you really think I would trust you with
a cgi
script)?
+xmlistconv is
a helper
script that reads the database and produces a html page listing all the mailers.
-I need to explain this thing at some point. Right now you just need to know that I count X-Mailer and User-Agent message headers.
-Here are the three scripts that collect the data and generate the graph
: [xmget|ftp

.hollenback.net/pub/xmailer
/xmget] [xmdump|ftp
