Does anyone know of any free, or very cheap, smtp relays that are ‘open’ to any sender address and not domain limited?

My email setup (my domain & also local sports clubs emails) is behind a residential dynamic IP (virgin media in the UK) so need a relay to avoid getting spam tagged; I have tried without a relay and even with having correct spf, dkim, dmarc, etc. Records lots of items were still getting tagged as spam for dynamic IP.

The challenge i have from testing most of the big name free smtp relay services (smtp2go, mailjet, blogmail, mailgun, etc.) is that I have a mix of imap/pop3 accounts and some ‘forward to x’ accounts, the imap/pop accounts are all fine however the forward emails are getting blocked by the services I tested so far because the sender isn’t from my listed domains. E.g. [email protected] sends to [email protected], my server then forwards the email to [email protected]. The services I tested so far are blocking the forwarded email because [email protected] isn’t in my allowed list of sending domains.

The setup was working using virgins (ISP) relay until today but seems they’re now limiting the sender address & have stopped even giving new email accounts to customers so not expecting any help from them so looking for options. (If the only real option is to stop the ‘forward to X’ I can live with telling the sports club that they can’t have that anymore & all their emails will need to be imap/pop3)

    I don’t think email is something you can really selfhost. I would suggest getting a cheap mail provider like mxroute. I am using a dodgey reseller with success yuzhen.cloud. If you pay for icloud you can use a custom domain with them.
