Hi All
We are planning to host WHM in Google and so require SMTP relay.
I've read some brilliant and not so brilliant articles on here, that have helped me.
Google requires instances to send mail via relay.
Sending Email from an Instance | Compute Engine Documentation | Google Cloud Platform
So far I have looked at :
Smart host.
Exim Configuration Manager - Basic Editor - Documentation - cPanel Documentation
We trialled exim with this config.
Exim 4 configuration for SendGrid - SendGrid Documentation | SendGrid
This would send emails but could not receive.
Wonder what other options there are out there ? I found this forum post.
Smart Host - Exim Cpanel - SMTP external outgoing mail server
I'd like some more clarity on the high level overview, would a simple postfix server with IP auth be acceptable to send mail on behalf of approx 200 domains ?
Also wondering if setting the MX records to the GCP instance is ok once the smart host config is done ?
Lastly does this set up have any issue with SSL certs and or mail headers and spf / dkim / anti spam when sending to sensitive recipients in Outlook etc etc.
Many thanks if you can join in with this discussion.
Kind Regards
Matt
