SMTP working but IMAP not

MattT

I need a little help finishing setup of Mailcow on my Ubuntu VM please. I am new to self-hosted email servers. I have confused myself into frustration and now just need to ask for help.

I am able to send mail, but not able to receive. I followed the suggestions of the tutorials regarding setting and am thinking I have overcomplicated things for myself. Here is my setup:
ProxmoxVE -> MailcowVM -> Nginx Proxy Manager -> Cloudflare -> SendGrid (not sure I even need SendGrid)
My domain is hosted at GoDaddy, but I set up Cloudflare for DNS to start migration off of Godaddy because of slow speed there).

Here are screenshots of configs:
DNS records in Cloudflare

SendGrid Authorization

MXToolBox results

Mailcow SMTP as I have it set up now

Happy to provide anything else needed to figure this out.

Any help is greatly appreciated!

I did a reinstall. Still the same situation. I sent an email to and email address that uses Office 365. When I replied from the 365 account, I didn’t receive the reply in Mailcow, and that 365 email stated my new self-hosted email wasn’t found on my Mailcow server.

Is there a place to add IMAP configurations? Are the settings in Cloudflare correct in the above image?

Should I remove Sendgrid from the picture to reduce variables?

Please help 😃 Thanks!
