There seems to be a growing backlash against Anti-Spam services out on the internet, the most recent that I’ve seen (from Blogger) is the Developer Dispatch. Personally I think the anti-spam filters are great but only if you get the option to unquarantine incorrectly blocked email, or even know that the isp is running a spam checker for you. I have run foul of this on my current hosting provider (who also handles my incoming email) in that it blocks all email from yahoogroups as it considers it all spam, and also uses spamcop. The YahooGroups is obviously a draconian overkill process, but what annoyed me is that there is no text to inform their customers that this happens. I only discovered it when emails I send out to a group were not being received by my own account and checking on the Yahoo page I discovered that the emails had been bounced back by the isp…..they were not interested in removing this block.
Another isp that I also use for another domain uses various blacklists, and several times I’ve found myself not being able to send emails to this account as either Pipex or demon have been blacklisted – this is one big blacklisting, stopping almost the two biggest isps in britain from sending email!
Personally, I think the best solution is to run your own spamkiller in house that can decide what is spam or not. I run a filtering option on my incoming email via my own mail server and I reckon I get about one spam a week making it past the filters…..Probably about twenty or thirty a day are being blocked by the filter options.
Remember, you can see my latest anti-spam decoder on my website which allows you to get my email address but stops bots picking it up and spamming me.
