is hitting on ham from a mailing list with the following subject line:
Subject: Re: [CentOS] mount UFS partition on CentOS 5.
A test email containing just the text "partition" in the subject line
also hits this rule so would appear to confirm my assumptions.
I suggest you open a bug for this. It certainly should not hit, as the
(?!tion) should keep it from matching an unobfuscated word...
But I think it's treating the middle "ti" in "tition" as an obfuscation
of "tion" hence the match in this case.
Does it hit unobfuscated "partitions"? How about "portion"?
Perhaps it should be /<post P3>(?!tion)<T><I><O><N><S>?\b/i
It hits partition, partitions, petition, repetition etc (basically any
word ending "tition(s)"), but does not hit portion, potion, nation,
notion or reputation, for example.
I'm happy to open a bug for this if that's appropriate, but the rule
does appear to be doing what it's designed to do albeit with some false
positives.
