Comment on Retain source IP when proxying through VPS
themoonisacheese@sh.itjust.works 11 months agoYou need a proxy for outgoing to avoid your source server being on a residential adress, which all but guarantees all mailservers using spamhaus etc will block you by default. DKIM and DMARC are needed in their own right but an SPF fail will already make your mail fall into spam.

Sure, but if you proxy both in and outgoing then your SPF record should of course point to your VPS and thus again not be a problem.

Indeed, but in that case an off-the-shelf SMTP relay works fine.
