I tried and it was absolute hell. I used mail-in-a-box and the setup seemed to work but there was a bunch of issues with serving and syncing the e mails. none of the guides helped and in the end i thought if i were to get it working i wouldnt trust it very much. Can’t be sure it’ll be reliable or if it’s gonna be blacklisted because some weird E-Mail thing isnt set fully correctly.

So it’s probably possible but I don’t think it’s worth the hassle
