You can actually set up gmail to send through an external server? I had no idea they’d support that. Running an SMTP server is absolutely not something I’m willing to do, though. Aside from the general setup/maintenance hassle, all the big companies are aggressive at blocking spam and private SMTP servers are just tough to keep unblocked these days (or so I read).

If you have GSuite you can, but I doubt it is possible for individual accounts. [1,2]

You can however send email to google's SMTP server, using an ordinary gmail account [3]. This is how email clients (Eudora, Apple Mail, sendmail) work. The only trick is that they force it to be authenticated and encrypted.

I believe (but have not verified recently) that if you send an email with an email address/domain other than of the authorising account, it will be delivered, even lacking all SPF etc. But, it will block for anything above small quantities of mail, and unless you set up DMARC for your domain, it will still get dropped or marked as spam. [4]

Running an SMTP server for yourself is actually fairly simple (okay, assuming a deep background in linux, but very educational). The real drama is DNS/DMARC/SPF/DKIM and users ruining your reputation.

It is, I do -- inbound email forwarded to gmail, outbound from gmail goes out through my server and while it's obvious it's from gmail, it doesn't actually include my gmail address anywhere.

Sending from Google's servers using my address would cause SPF and DMARC failures, so if you want to do that then they'd have to make sure it's clear that the mail is actually from gmail.

Last time I tried this they forcibly rewrite the sender as your gmail account.
