Changing ISP's is a headache that causes addresses to be lost and it
also time consuming to switch over.
I now use Mozilla Thunderbird, it comes with a junk mail filter that
trains itself to recognize junk mail. You have to manually filter the
junk from the start but over time it starts to recognize junk, i.e.
certain repeated words (viagra, etc.). It filters 25-50% of the junk on
any given day so I am manually filtering the rest. It is a pain but I
rely on email. Lenders prefer to communicate via email, so I routinely
receive condition sheets regarding loans and now receive all rate sheets
via email from my efax account.
