I like the new Email Routing Insights. It’s great to be able to see what’s going on with mail coming to my email routing addresses. But I’ve run into a couple of issues.
-
Very little info about mail that was not delivered due to Error. All I can tell is that Cloudflare did not deliver it to the destination address for some reason. As far as I can tell, there’s no log of the conversation between Cloudflare and the destination server to help figure out why the mail wasn’t delivered successfully.
-
The ability to filter the log by Custom Address only works for specifically-defined Custom Addresses which are populated in a drop-down. There is no ability to manually enter an address to search for. I’m using catch-all, and there’s no way to filter on messages to [email protected] if that address is not specifically defined as a custom address.
-
The address that shows up in the Custom Address column appears to be the address in the To: header of the email (or maybe the CC: in some cases). This is often not my address. For example, many mailing lists put the list address in the To: header, and that’s what Cloudflare shows in the Custom Address column. The address that actually receives the mail is in the SMTP envelope (effectively the same as a BCC), and that address doesn’t show up in the log.
