Not receiving e-mail on Outlook Express/ win 98

[prmac]

Hi, I seem to have a problem; I am not receiving e-mails, especially E-Bay notices( which I get quite regularily). I was receiving them fine, (along with lots of junk mail) including updates from this site which I still do receive.
Leading up to this problem, I was away for a couple weeks and so did not check my mail, I came home and tried to sign onto the internet but was unable. I worked with my server provider and was told I probably needed a new Modem. I replaced the modem and got back onto the net but when starting up Outlook Express (on Win98), Outlook was looking for a different Connection name. I corrected this and I received all my back mail along with about a hundred pieces of junk. Through Tucows I downloaded a trial version of Spam Bully. Now I received only mail from this site, which was routed to Spam, which I rerouted, and another site I get regular updates from. There was nothing else in the Inbox, Spam file or unsure file. Where could my mail have gone? When I looked into the E-mail details and see that some of my address book friends are listed as spam. I diabled Spam Bully then later uninstalled it but I am still not getting my mail - Can anyone shed any light on this- suggest things to try?

An update:
This morning I began receiving my e-bay notices. I have not received anything else, including junk mail.
Is there any Spam control anyone can recommend?
