I regularly send mailings to groups using the WLM "Categories." It's not practical for me to type the names of the individual members of each group. I find now that these categories don't work, at least for BCC mailings. (I haven't tested the CC mailings, for which I have less use.) The mailing goes out with the category names correctly in the BCC field, but then when I check the sent mail and look at both the Details and Message Source there is no indication that any of the BCC copies were sent; and indeed intended recipients have told me that no such emails came through.

I used Outlook Express happily for many years without any of the multitudinous problems I've encountered with WLM, of which this problem is the worst. I simply cannot continue to use WLM if I can't send group mailings as BCCs, nor can I spend hours and hours in an attempt to fix the issue. Is there any solution or do I have to switch to another email provider?
