1 year agoI wouldnt say that. however setting uo your own mail server is a lot of work, as you have to abide a lot of “security” rules (SPF, DKIM, DMARC, rDNS). Additionally some hosters reuire you to apply for port 25 to be unblocked (e.g. hetzner)
Well I did set one up today and the mails land in the spam folder for GMX, GMail and Microsoft (@live.de), although I set up SPF, rDNS, and DKIM. I have to take a look at how to setup DMARC, beacause my domain hoster doesn’t allow free configuration of the TXT entries, you have to use templates and there isn’t one for DMARC
