MIMEHeader question
Hi all, I have a question about the MIMEHeader plugin: if I have multiple mimeheader rules, are they all checked against the same part in a multipart message? So let me give an example: Let's say an email has 2 separate mime header sections (perhaps one is TXT and the other is HTML, or perhap there are 2 file attachments, or whatever). They might look like this: --=_NextPart_000_0062_01C7099B.069AFD30 Content-Type: image/gif; name=Blank Bkgrd.gif Content-Transfer-Encoding: base64 --=_NextPart_001_0063_01C7099B.069AFD30 Content-Type: text/html; charset=iso-8859-1 Content-Transfer-Encoding: quoted-printable Then let's say I have a couple of mimeheader rules as follows: mimeheader __RULE1 Content-Type =~ /image\/gif/ mimeheader __RULE2 Content-Transfer-Encoding =~ /quoted-printable/ meta MY_META_RULE (RULE1 RULE2) My question is, will the meta rule trigger, or not? Because as you can see, only the first mime header section contains Content-Type: image/gif, and only the second mime header section contains Content-Transfer-Encoding: quoted-printable. So are my two mimeheader rules being run against each header section separately from each other, or are they only run against the header sections together, and thus BOTH must fire on the SAME header section in order for the meta rule to work?? Cheers, Jeremy

Okay - so you're saying that the two mimeheader rules will actually run separately from each other, on each header section, and thus the meta rull WILL trigger? That's actually not how I'd want it to work. Is it possible, then, to have a meta rule (or some other method) using the mimeheader rules, that will ONLY trigger if both mimeheader rules trigger against the SAME header section? ie. all elements searched for by all mimeheader rules, must exist within the same header section - is this possible? Or do I have to resort to a 'full' rule or something?
