Yo all ! I just upgraded an old Outlook 6.x express to TB. To my surprise the mail filter apparantly misses an essential functionality. You cannot filter a mail address on it's domain, but only on the entire mail-address. So instead a single filter on "@hotels.com", You must create a filer one each (new) name that appears, like offers@hotels.com last_chance@hotels.com spam@hotels.com etc... etc... And especially those ...pain-in-the-a***... rayban sunglass spammers, that change name every week cannot be filtered (thay know that TB misses this, so thats why thay do it). This lack of funcionality is allso decribed in the online doc. with the use of the "from" and "is" in the filter rules, which only takes the full address. COME ON MOZILLA - make the (simple) patch, so We can sort out an entire domain instead of that bird-picking. I thought I upgraded from Outlook Express, but apparantly not, because this functionality has been there since ages... Im soon looking for another client.....
