I have used Nfilter for such uses, but it is an old cranky program. 
You can set it to avoid messages sent from a specific site, or from 
Yahoo, or from  specific persons, certain words in the heading, even 
for posts sent to more than, say, two different newsgroups.  Not sure 
about for certain words in the message, though.

Allegedly you can set up a Custom filter header, but I've never seemed
to be able to get that to work...in Filters/Edit/Customize I'd set up a
Header called Body or Message then add a Filter entry for if
Body/Message Contains =ybegin, Delete Message.

Anyway, that's what I'd try - if I've got it wrong (most likely the
Body/Message Header reference...that seems too easy) and anyone knows
better, please enlighten the both of us.  I'd like to use this sort of
thing myself!



I'm not sure, but I think the filters work only on headers.



Yeah - that's where I get confused.  The Customize dialog says new
message header; does that mean a system generated header in the
message, or the new header label that the user adds which appears in
the drop-down list?

It works with Subject, To, From, Date, and Size by default - how do
those relate to header information?



Yeah, I've checked the full, raw E-Mail and nowhere is there a header 
that says Body: or Message: so I don't think it'll work...

Re: Yenc decoder

2010-02-24 Thread MCBastos
Interviewed by CNN on 21/2/2010 15:47, Rick Merrill told the world:

 Only advantage of yenc is that it can break up a posting into several 
 parts and the user can put them together again.

Actually, no, it does that in a very brain-damaged way, by relying on
the SUBJECT line. There are better ways of doing that.

And it also identifies the data block in a way that's only a slight
improvement on the way UUENCODE uses, while MIME has solved that problem
ages ago.
Because of this, there's a problem with yEnc sometimes being detected as
binary and being re-encoded as Base64, which not only negates the yEnc
size advantage but may end up breaking the attachments.

There's a proposal to use yEnc encoding within a MIME framework. That
could be nice, since the real advantage of yEnc is that it uses 8-bit
encoding, instead of the 6-bit encoding used by Base64. Unfortunately,
current Usenet binary groups seem stuck into the it's good enough
mindset and nobody is trying to finish the proposal.

Might I humbly suggest that if you want to do binaries, you read those groups 
with pan. It handles virtually all of the diverging variants of yenc, and is 
particularly good at displaying or saving binaries.


I will add that for text newgroups it is one of the least-featured clients I 
have used, and as a former head of a national ISP news server group I got to 
test a lot in handling user complaints.

Well, the Mozilla project is all for following (and fostering)
standards. The problem is that yEnc is not a recognized standard -- and
besides, it has serious design flaws. And you should think twice about
implementing/endorsing a spec that *its own author* criticizes...

No, that can be done with the MIME encodings as well.  The advantage of
yEncoding is the size/bandwidth saved.

From what I've seen, yEnc isn't particularly well supported...or 
standardized.


I subscribe to several 3D artists binary groups and sometimes I can see 
yEnc posts with SM and sometimes I can't - I generally chalk this up to 
some server in the chain not knowing what to do with yEnc, or a poster 
switching to a newer version of yEnc that a server (or client) hasn't 
kept up with.  I've seen that on several occasions when I've been able 
to see someones posts and suddenly can't - the poster then usually comes 
back and states that he has upgraded or switched versions.


...what I'd rather see is SM being able to support multi-threaded 
images; ones which are too large and are automatically broken into 
serial posts.  That should be more doable.
