Many spam messages can be caught by checking if there are more than 5 addresses in the To and CC fields. So what about a filter that would just count the number of addresses and if this number is bigger than the one specified in the filter, the mail gets caught by it. Example [Move to folder] messages with [To and cc] more than [5] addresses By the way, this would also be a way to catch "business spam". You probably seen this in your company that some messages just get distributed to huge lists, but nobody in fact is really interested by the content...

This might be valuable for some people, but many folks use real/valid mailing lists for both personal and business use in distributing mail of interest.

Right, so it's even more suspicious if you have 5, 10 or even more addressees... As much as I could observe, these mails usually are 1) Spam 2) Virus hoaxes ("Please send this to everybody...")

No, you missed my point. Many, many addressees are often valid emails.

This doesn't sound like a good idea to me. It is like new filter enhancement request just because one wants to set up a filter like that.

*** Bug 164654 has been marked as a duplicate of this bug. ***

"Many, many addresses" emails are often emails that are not useful. The reason why filtering on a specific count would be good, is so that people could make that decision on their own. It's a new filter enhancement request, because it is currently impossible to setup a filter like this in Mozilla. I'm a little confused by Navin's comments about it being a request just because it's something some people want to do. Isn't that what "severity: enhancement" means?

mozilla.gv4r@snet.net, yep, you're right, that's what RFE means. And I think Navin and laurel missed a point: They just have in sight the corporate use of CC or multiple To addresses. While this is a bad practice anyways (it tells you you don't have to do anything, somebody else on the list will surely do it instead of you), it's just something I encountered in companies. For a private use however, you rarely use many, many addresses for your regular mail. I've got a yahoo account with at least 50% of all spam being with more than 10 to-addresses. My understanding of this is some people will need it (some are even requesting it) and some won't use it because they don't need it. But that's what happens to most of the features in Mozilla, right?

I have to beg & plead w/ you all to *please please* incorporate this feature! It will be *the* spam killer. While the responses are "true", they still aren't really "justifications" for not adding the feature. For example, I already know the mailing lists I'm supposed to receive, and they are already filtered off into another folder. [Alternative work around is to use a specific email address only for the mailing lists.] Then from what is left, 100% of messages with more recipients than just me are spam. So I need a way to catch & trash all e-mails where "To: or cc:" contain more than just my email address. [Currently one can set "[To] is [your email address]" and "[cc] is [your email address]", but this falls down when you have a *lot* of aliases going to one catchall email account. Right now there is no "[To or CC] is [...]" option, which would probably get me halfway, but would still require writing a lot of filters for each alias.] It doesn't seem like it would take that much to count the number of recipients. And, agreeing with the above comment, some people will use and some people won't. Saying "this won't be of use to some users" is bad logic - not all users use "filters", but I'm hoping you won't get rid of them altogether just because not everybody is using them. I'm currently deleting about 60 spams a day, and this would be (as far as I can tell) the only way to just dump them all the trash automatically.

mass re-assign.

almost 3 years later - is anybody looking at this?

sorry for the spam. making bugzilla reflect reality as I'm not working on these bugs. filter on FOOBARCHEESE to remove these in bulk.

Filter on "Nobody_NScomTLD_20080620"
