Self hosting email goes in one of 3 directions:
- fuck, half of my critical services think I am spam
- fuck, why did I spend so much time for this shitty inherently unprotectable shit (email is unencrypted)
- this is great and I love it! (Who are you people??)


Most likely can’t and shouldn’t bother. Keep your private stuff on your private devices.
But if you really really want to, go to IT well prepared with all the changes you want to make and see if they allow it.
