I've always turned off the spam filtering option with my webhosting providers (one of which is currently Dreamhost)
As no control over false positives has been a concern for me. These days I download all my messages and feed them through spamassassin and dump them into a local mailstore. I had envisioned pushing them back up somewhere so that I wouldn't be tied to my home machine for email, but I never got around to coming up with a solution for that. I used to go let Thunderbird do the filtering/learning...but I had switched due to the move to Office365. With Zimbra, filtering takes priority over the move to Junk, so I could just filter common false positives into a folder. Office365 doesn't care about my filters....and its like 50% false positives.... Partly made worse, because students don't like getting all the official email blasts they get, so they keep training the system that its junk. Though another department the part of the staff kept training the system that emails from their office staff (scheduling department meetings) were spam....which led to an angry ticket on what is Zimbra sending office emails into spam. We could get the feedback learning disabled on our Zimbra, since it was a hosted environment. Not sure what progress, if any, has been made with Office 365. So, I have fetchmail download my inbox and my junk folder....and then I decide what is spam (which seemed to be a lot less than I expected, until I had missed a line in my procmail filter in edit in April. The biggest issue is figuring how to stay connected to email when I'm mobile. I haven't worked on figuring out how to estimate what it would cost me to move the local processing and storage into a VPS or such. I do clamav on my home system as well, as I have also been on the fence on whether to use that from hosting provider, since some incorporate 'spam' checks in virus filtering (I'm guilty of doing that at work) Where virus check is main a pass/reject filter, versus spam check yields sense of its spaminess, which requires processing if reject/drop/move as desired. Wish there was a spaminess plugin for roundcube. The email address I use with ebay is one that I have opted out of virus check with....more because blocklists are part of the viruschecks. Every now and then, there'll be an ebay seller running a mailer from home ISP network, which aren't supposed to be able to do that. Though I've been working on hacking my sendmail to connect the appropriate authenticated smtp service and authenticated for the specific address I'm sending out as. Probably should do that before the SPF record of service I had been using get's yanked out. The include: incurs 9 DNS lookups, which in my SPF causes the limit of 10 DNS lookups per SPF check to be exceeded. As for the quote....I'm lucky if I read 1% of the email I get each day...and a lot of what doesn't get read includes work email (and lopsa email goes to my work address...) Some days I barely make it through the handful of emails in my 'priority' inbox at work. (especially if it takes all day, or longer, to do what is asked for in the first email I read...)
