hi,
in thunderbird, while creating a new filter, i have an option like "if [to/cc/subject] begins with"..... but in zimbra, that 'begins with' is not there. i tried going with matching a regular expression like ........^expr........ but those mails are not getting filtered. and also the 'X-spam-detected' feature in thunderbird looks to be missing here in zimbra.
can someone help me with these two things?
