we have had an exchange server at work for years. our email is

unfortunately, it is not working well. if the filters are too tight,
there are many valid messages that we are never receiving. on the
flip side, if the filters are eased up....we get loads and loads of
spam.
Yes, that's the sad truth.
there are also emails that we send out that are being blocked
by others as spam for some strange reason?
Difficult to say, but you might get an SPF record for your domain & make
sure you've got a PTR (reverse lookup record in DNS) for your public IP
....your ISP has to take care of the latter.
we would like to have someone else "host" our email and deliver it to
our exchange server after properly filtering out the bad emails and
only sending us the good ones. Any suggestions?
A lot of companies offer this service. Check out www.mailfoundry.com or
www.postini.com. The latter has been around for a long time and works well,
but I've recently begun to favor MailFoundry, as they also send a "daily
digest" email to each user so they can easily see what's in the quarantine &
release it. You're always going to have the problem of false positives, and
spam that gets through - the important thing is that your users have access
to the quarantine so they can rescue things that need rescuing.
