[Mimedefang] Suspicious msgid's

[scuba at centroin.com.br]

Hi all,

	Recently I've noticed many spam messages whose msgid seems to be
similar, like these:

msgid=<0-$6yay6-5$i24 at 0nhbqx.7kx>,
msgid=<22mof$-o-qlnr0$j$1 at 34to.k.0z1cdl>,
msgid=<o$xv-8$5o8h0$5$n at aws.5gd1a0r2>,
msgid=<8lkhtg$g-855-8a-4$q at yedpa95c>,
msgid=<gseul-b-57pkr6-zm1k36-5z17-02 at c9k2.b.th>,
msgid=<lrk4d$$kw8-$$0f-abx$g6$$ru431 at 4dp8uyfp>,
msgid=<at002-$1$8-u9$-$--89k1ladn at 8y5.j.1xaxdn>,

	Anyone else have seem this? I'm working in some rule to SA/MD to
catch it, but I would like to see if you have already done something.
