Mail management with Cloudflare

[Old Nick]

This is how i set mail in XenForo and Cloudflare :

• Cloudflare :
  • I created a custom address : XYZ@permaforo.net
  • Routing rules : XYZ@permaforo.net > Send email to > XYZ@icloud.com
  • there are Cloudflare SPF and DMARC entries too.
• XenForo :
  • Default email address : XYZ@permaforo.net
  • Contact email address : XYZ@permaforo.net
  • Email transport method : PHP built-in mail system
  • DKIM email authentication : XenForo is signing your outgoing emails with DKIM (I entered the settings in CF)

Well, all seems to works fine, contact form works fine, test email works fine, following content with email works fine...
So now i used a "virtual" email address XYZ@permaforo.net for all emails sent/received to/from my forum permaforo.net.

So I didn't even create an email address from my domain name via my registar.
But it all seems so simple to me, am I forgetting something, what are the disadvantages for such a configuration? I would like to point out that my forum is very inactive, so there are very few emails sent, and even fewer received.

Thanks.

Where do bounced emails go?

How are you handling bounced emails?

You probably want to set up a separate mailbox that you can access via IMAP (and is used for only this purpose) and then set the bounced email address and automated bounced email handler in the XF Email options.

Hint: the bounced email address really needs to be part of your domain - so set up another cloudflare alias for it.

Can i access to "virtual" email created in CF via IMAP, what are the settings?
Sorry, i understand nothing in this matter...

(Sorry for the ping-pong between this thread and the sparkpost thread !)

No - you need to set up a new mailbox on Gmail, Outlook, iCloud, or somewhere else and then set up a virtual email in Cloudflare that redirects all mail to that mailbox. Then you set up XF to retrieve bounced emails via IMAP from that mailbox.

Ok, so i will use the IMAP credentials from Gmail (for example) here, correct?



But this field is filled with the virtual email address set in CF?




Assuming i set a routing rules from the virtual CF address created for boucing to the Gmail address

And now the question that kills: What is the point of getting bounced emails in a mailbox?

So that the user accounts you're sending to which are bouncing, are automatically disabled to prevent you from continually trying to send them emails - which is one of the signals that will get your IP address and domain blocked from sending emails by various email providers.

It aids with mail deliverability.

@Sim Is it still possible?

I copy/paste the password so it's good, i guess my previous message could explain this error.

Seems to work now with OAuth

 

[Sim]

Yes, you need to use the Google OAuth method for Gmail - not IMAP.

Thanks for your help @Sim
