@KarnaSubarna are you referring to a selfhost signal proxy instead ?

@curry after i setup everyrthing I had no deliverability issue. But i had to use an external SMTP relay because of my isp filtering traffic on port 25. That adds an extra fixed IP layer that may provide a better IP reputation idk. I rent a cheap 1.2€/month vps for that purpose.
I get listed in spamhaus because of a dynamic IP, but my relay isn’t listed (at least not in not scam blocklist). Anyway I send mail, to gafam or whatever and people reply back.
I send 2-3 mails a week, maybe it counts.

@Paddy66 it depends.

I host everything, including website and email server behind a regular dynamic ip for years.

And no I don’t get block by any gafam.

But I am lucky because my ISP doesn’t change that often (maybe twice a year). And my domain provider provides an API that my ISP router can use to update my IP automatically.

It may work, it may not :)
