I have a filter for mails starting with "*****SPAM*****" with the actions deleting and marking as read. Marking as read is only done when I use "move to folder: trash in (...)", it doesn't work when "delete message" is set.
Which program are you using, and which version? See bug 243832 and bug 201917, which are both about the same problem and which have been fixed for over a month. > it doesn't work when "delete message" is set. What is that supposed to mean? There are three options for how to handle deleted messages under IMAP, but none of them are called "delete message." Incidentally, if you use the "delete" action in a filter, "mark as read" is implied; you shouldn't need to specify both.
> What is that supposed to mean? You're right, I'm using the German language pack and translated it. And it doesn't occur anymore. Probably I added this to my personal "open a bug report list" with 0.9 and because I didn't update immediately, the date was after the 1.0 release.
Nothing in Mozilla was broken or fixed. -> WORKSFORME
It was broken and already fixed in 1.0.
