[Gllug] OT: Unwanted email

[David Abbishaw]

Sorry for the off topic post but I need some advice and thought that this is
probably the best community I know and unfortunately this doesn’t relate to
Linux at all – and both the mail and filtering software is windows based.

I recently setup some mail filtering software (sorry trying not to use that
word that’s not ham) for my home domain of 5 email addresses.  I was fed up
with receiving something like 150 - 300 rubbish email a day.  All went well
for the first few weeks and dropped incoming mail down to about 10 junks a
day.  So in a bid to reduce it further I started reporting these domains to
spamcop, that was about 5 days ago.  So since then junk email per day has
risen to a peak at 62'000+ per day (see stats below)  Ands it beginning to
affect surfing and the time to deliver legite mail to the mailbox server.
~40 mins on average.

So really what should I do – I guess I need to stop reporting these people
to spamcop as it appears to have made a huge difference (and at the moment I
wont recommend it to anyone and there is a warning of sorts on their
website.). Upgrade my internet circuit?  Wait and it will disappear?  Im
lost for what to do next at the moment.   

So any advice or any one that has been through the same thing I’d like to
know what your experience was.

Here’s the stats if anyone is interested.  Neither of my mail servers will
relay non local mail and seem fairly well secure for windows boxes.
