Did you block the exact address or did you block all addresses ending in the domain name?
Example: did you block
[email protected] or did you block LINK.COM?
If you blocked LINK.COM then you won't get any messages from there. Some software, like MS Exchange, allows filters to move items. I used to have filters to move exact addresses to particular folders, leaving all unwanted/unclassified items in the Inbox. Anything I wanted to keep got a filter to move it. Anything else - wipe the inbox to the trash. That way I didn't miss anything and didn't spend much time on junk.
