long spam subject fields

[junk]

Hello everyone, I'm getting spammed with emails containing long subject titles, such as:
MMlaleEnhaancemmnentMedicationsAreAvailableAllOver TheWorldBbuttHereWeSellOnlyBestMeidcicnes.

I could easily get rid of them if I could generate a filter for any emails containing words of more than, say, 20 chars in the subject. Virtually none of those are legitimate. Does anyone know whether there is a way to do this in Zimbra? Also, is there any way to write a custom external filter, like a plugin? I do reasonably well with C, Basic, Pascal and could easily write code to filter this type of spam, e.g. by looking for an unusually high incidence of duplicated letters or an abnormally large number of symbols like \ or /.

What's wrong with the anti-spam system on your Zimbra server? Why aren't you marking those emails as Junk?

I don't understand? The exact wording in the headers obviously changes, as do the authors and the message content. How can I create a filter for messages containing words of more than 20 characters so I don't have to erase them manually every day?

Highlight the email then click on the Junk button above the list of mail in the Web UI - this will train your anti-spam system to recognise them as spam. If, after a couple of day, you still have problems with receiving emails like this then I suggest you contact you mail administrator and ask them to look at the problem. As you've already seen it's not possible to create a filter for a specific length of Subject.
