Hmm, no I will tend to agree. We have made some changes to our spam filtering including introducing another server tonight. IMO (well and by the stats) spam has increased markedly in the last perhaps two weeks. We were receiving 200ish messages a minute at the beginning of the month and now it has approx doubled. Even with what I consider good/excellent spam filtering I have personally seen an increase in un-wanted email. Odd really, but the "we have a free atm card" and "you haven't paid your ebay bill" and finally the good old "we've reviewed your bank account details and click here to amend" emails seem to be the favourite BS at the moment.
Having said that, another SpamAssasin server in place and I am pleased to say we have returned to queue deliveries in seconds, rather than the dismal 4 minutes we had mid afternoon. Blooming un-solicited ******
