I have a suggestion for functionality. One is the ability to create global filters (e.g. for spam), and the other is the ability to create filters by right clicking as in K-mail. K-mail has a feature where you can right click on a message to create a filter. In thier case, one rule offered by right clicking is "reply as message undeliverable". Having a global rule will simplify spam management and be a major point in favor of Mozilla (untill copied). I suggest that a global filter (for all mail accounts) be made available by right clicking: One one option would be to copy the message charachteristics (from, subject, ...) to the filter creation screen for that account; with a spam option marking the sender a spammer & sending their messages to the trash upon reception (on all accounts). It is true filters can be created in the current system (By clicking tools (alt-t)and message filters (i, -enter), then choosing the mail account for the filter, and then editing or adding a new filter.) However, a global filter is a nightmare to operate, and spam is out of hand. Thank you for your work.
Please, always report only one problem in each bug. This one is a dup, see bug 34973, bug 129883, bug 10097 and you can click in the From of a message to create a new filter. *** This bug has been marked as a duplicate of 34973 ***
