.SH NAME
sa\-awl \- examine and manipulate SpamAssassin's auto\-welcomelist db
.SH SYNOPSIS
.IX Header "SYNOPSIS"
\&\fBsa-awl\fR [\-\-clean] [\-\-dry\-run] [\-\-min n] [dbfile]
.SH DESCRIPTION
.IX Header "DESCRIPTION"
Check or clean a SpamAssassin auto-welcomelist (AWL) database file.
.PP
The name of the file is specified after any options, as \f(CW\*(C`dbfile\*(C'\fR.
The default is \f(CW\*(C`$HOME/.spamassassin/auto\-welcomelist\*(C'\fR.
.SH OPTIONS
.IX Header "OPTIONS"
.IP \-\-clean 4
.IX Item "--clean"
Clean out infrequently-used AWL entries.  The \f(CW\*(C`\-\-min\*(C'\fR switch can be
used to select the threshold at which entries are kept or deleted.
.IP \-\-dry\-run 4
.IX Item "--dry-run"
When specified with th \f(CW\*(C`\-\-clean\*(C'\fR option it displays the infrequently-used AWL entries
that will be deleted. The \f(CW\*(C`\-\-min\*(C'\fR switch can be
used to select the threshold at which entries are kept or deleted.
.IP "\-\-min n" 4
.IX Item "--min n"
Select the threshold at which entries are kept or deleted when \f(CW\*(C`\-\-clean\*(C'\fR is
used.  The default is \f(CW2\fR, so entries that have only been seen once are
deleted.
.SH OUTPUT
.IX Header "OUTPUT"
The output looks like this:
.PP
.Vb 1
\&     AVG  (TOTSCORE/COUNT)  \-\-  EMAIL|ip=IPBASE
.Ve
.PP
For example:
.PP
.Vb 2
\&     0.0         (0.0/7)  \-\-  dawson@example.com|ip=208.192
\&    21.8        (43.7/2)  \-\-  mcdaniel_2s2000@example.com|ip=200.106
.Ve
.PP
\&\f(CW\*(C`AVG\*(C'\fR is the average score;  \f(CW\*(C`TOTSCORE\*(C'\fR is the total score of all mails seen
so far;  \f(CW\*(C`COUNT\*(C'\fR is the number of messages seen from that sender;  \f(CW\*(C`EMAIL\*(C'\fR is
the sender's email address, and \f(CW\*(C`IPBASE\*(C'\fR is the \fBAWL base IP address\fR.
.PP
\&\fBAWL base IP address\fR is a way to identify the sender's IP address they
frequently send from, in an approximate way, but remaining hard for spammers to
spoof.  The algorithm is as follows:
.PP
.Vb 2
\&  \- take the last Received header that contains a public IP address \-\- namely
\&    one which is not in private, unrouted IP space.
\&
\&  \- chop off the last two octets, assuming that the user may be in an ISP\*(Aqs
\&    dynamic address pool.
