Reflections on running my own mail server for 10 years

> (1) The risk of getting filtered.

Really a problem for mail. The US seems to be hit especially hard because everyone made a Google account.

It is better in other countries. I think gmail is atrocious and most importantly insecure. Mail is not a highly secure form of communication, but I would expect my mail not getting read. This is actually one of the worst case scenarios for it but people don't seem to care.
