I am using out look express with windows XP home
about a month ago I stopped getting my news group e-mails (do not know why) now it has gotten to the point that I do not get about 80% of the e-mails that are sent to me and it will not deliver e-mails to certain people. there is no rhyme or reason to what it is doing but I need to figure this out. I make my living on the internet and it is getting very hard to keep people happy when I dont thier e-mails.
any suggestions??????????????????????????

Any chance your ISP has installed a spam filter on their email servers? More and more ISPs are doing so. If that's the case, your ISP should have provided you with an URL to access your account's filter settings so you can configure them the way you want.

In addtion, spam filters on the recipients' ISP's mail servers may be stopping your messages. The recipients will have to take care of that on their end.
