Is there anyone who used Gmail relay SMTP with Cloudron??

[p44]

I would like to buy Google Workspace services and use with Cloudron as email relay option.

This is because several providers still see sent emails as spam.

My question is: is it possible to use a single Google Workspace account as a relay for all mailboxes on a specific domain?

Thank's a lot for your support and patience.

@p44 I am not familiar with what exactly Google Workspaces is with regards to relay, but if you struggle with email delivery then we already do support a couple of mail relays https://docs.cloudron.io/email/#relay-outbound-mails anyone of them will likely improve your situation.

I think https://support.google.com/a/answer/2956491?hl=en is the workspace docs to set up relay.

@p44 I've set it up with EspoCRM. It's a bit of a nuisance going through their docs to do it without using their dumb Auth system and there's lots of bullshit warnings against changing the settings to allow you to do so, but it is possible with some determination, confidence and wading through their misleading documentation.

@marcusquinn got a better writeup?

@nebulon Thank's a lot, now I'm trying Postmark
@girish Thank's a lot, as @marcusquinn wrote, is a little bit nuisance going through their docs...

As most of us knows here, Spam is a pain point of self-hosting solutions...

I checked also "Warm up" services... but I don't want they put the hands in my or my customers inbox...

Also, most of services like Mailgun, Mailjet, they're for mass marketing emails and for transactional emails, not for different kind of use.

@robi Nope.

@p44 I was a Google GSuite user for >10 years and in my experience its spam detection is pretty average to poor.

The only service with good spam detection (in my experience) is Protonmail, which is now my main corporate and personal email hosting.

@timconsidine
https://mailbox.org/en/ has also very good spam detection, is privacy conscious (inter alia data centers in Germany, anonymous registration possible, etc., see https://mailbox.org/en/security) and offers quite easy end-to-end encryption. Works reliable as an smtp-relay for domains as well (no deliverability issues).
