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