[Evolution] Filtering out those annoying PowerPoint attachments

[Jeff <web kiddo free fr>]

You may know what it feels like. Friends and family members continuing to send you their 2 MB .ppt crap to your inbox even though you asked not to received it.

I am looking for a way to set up a filter to throw them in the garbage automatically. It would be even nicer if it could send an automated templated reply to say that it has been automatically trashed, but I think Evolution filters don't have this feature.

I'm looking for advice on setting up an effective filter with no false positives. Any experiences or ideas, folks? So far, what I've come up with is this filtering rule (all conditions must match):

- File attachment: EXISTS
- Size (Kib): OVER 1500
- Receiver/to: IS NOT [my email address]*

*: I am assuming that this means that if there is more than one person in the "to:" fields, then it will get filtered out because it's not "only" my address.

Any ideas on making this more effective?
Cheers.
