To remove only the relevant items (not recurring) you need to parse the 
calendar items. The simplest parsing is to grep for RRULE attribute in 
the iCalendar data - that sets up recurrence rule. This even works when 
you filter a Calendar folder on messages that contain RRULE in 
Thunderbird or WebUser.
