Spam filtering on your own mail server is easy. 99% of spam are generic automated E-Mails that are sent in bulk with lots of spoofed metadata (domain, sending address, date, etc.). I have an address on a domain that used to be hosted by a third party and it got tons of spam. At some point I moved the domain to my own server with mailcow, and it blocked the vast majority of spam out of the box with no false positives. It uses rspamd, not sure if they have a tweaked config for it or something
Generally I really like mailcow. It makes dealing with all the ugly parts of hosting E-Mail fairly simple
- berkes 5y agoI'm using mailinabox, very similar to mailcow. Before that, did all the config myself. Incoming spam is hardly a problem. Spammassassin, rspamd and those catch most. Greylisting the rest. Once a year I see an uptake in spam, spend a few minutes dilligently marking everything a spam/not spam which the server the uses to retrain itself a little. Spamfilgering when selfhosting is hardly more work than on gmail, live, proton and such. Your outgoing mail icw spamfiltering, however, is an entirely different, and tough problem.
