What makes the Elipse and for that matter any use of a period inside the
subject line so bad is that most filters rely on regular expressions to
filter. The period is a special character in regex processors which
means all. If one were to create a simple filter based on the period,
they would be blocking everything. So this trick is utilized to get past
those filters.

jesus christ then give that filter some score points instead unconditional block as well as train your bayes and use DNSWL with negative scores

last but not least add that line to your SA local.cf
whitelist_auth *@lists.fedoraproject.org

A manual creation of the filter which would include \. would be required.

so what - you need to take care about escaping in general

Until I created the filter to block out elipses. I would get all sorts
of bad mail trying to sell me all sorts of stuff that you would not want
sold to you, or to visit all sorts of sites you would not want your kids
to visit. So, to answer your question, yes I have blocked elipses for a
very long time. I will continue to block elipses, and I am quite
confident, because of this issue other aggressive filters will also
block them.

you do that because you are simply too lazy to train your filters because otherwise we would not be able block that sort of mails without creating hammer rules with false positives

You can do what you wish. I am not going to get into a trolling match

well, you started the trolling with your "i am unable to configure a sane spamfilter and so ask the world to write around it for legit mails"

with anyone. I am relating my experience and made a request thats all.
If you choose to continue using elipses thats fine thats up to you. :)

honestly if you would have expierience with spamfiltering you would write sane score rules instead ask the rest of the world to take care how to write their mails for not hit your broken configuration

Believe it or not.... it is.

A quick search on this list shows over a hundred such messages over the
last few years. Similar searches on other lists show similar results.
Are you saying that all these messages have been blocked by your spam
filter? If so, you seriously need to think about changing it
