User Agent: Mozilla/5.0 (Windows NT 6.1; rv:5.0.1) Gecko/20100101 Firefox/5.0.1 Build ID: 20111230031151 Steps to reproduce: I am trying to filter incoming mail by the "Delivered-To" header. The mails contain two "Delivered-To" headers – one being my individual mail address and one being the mailing list address it was originally composed to (BCC). I created a custom field Delivered-To and set up a filter to move the messages to a sub-directory. Actual results: Filtering works for the first "Delivered-To" header, but not the second one. Expected results: The message filter should look at all headers and not just the first occurrence.
is it and or or and and close in your filter ?
I originally had two filters applied — but tested it with only one rule now. No difference (hence no difference with either AND or OR). The Delivered-To rule is set to "contains".
I've had other requests for this wrt FiltaQuilla. Looking at the core code at http://hg.mozilla.org/comm-central/diff/7b75008cb771/mailnews/base/search/src/nsMsgSearchTerm.cpp we do accumulation for the received header, but not for delivered-to. So this is a legitimate request. The core change would not be very difficult - though not sure if there are any negative ramifications of doing this.
