Some Incoming emails are delayed and some outgoing emails never arrive

I've had my own GoDaddy domain for 20+ years and I use the GoDaddy email forwarding to forward my email to my comcast email account. I have no GoDaddy mailbox. I am seeing more frequent cases where some of my incoming email gets delayed for hours. I'm using outlook connected to my Xfinity email account to send email. Some of my emails never arrive, others are delayed. I had ChatGPT check my DNS records and it indicated that records such as DKIM could be added to the Xfinity DNS to correct the problem. Is this something that can be done or do I need to stop using Xfinity email?

user_dg57r Xfinity applies DKIM signatures automatically to outgoing emails sent from Xfinity email addresses to verify the sender's identity. However, Xfinity does not allow users to add custom DKIM signatures for personal, third-party domains hosted on their servers. 


Key Details for Senders:
Outgoing Xfinity Mail: All emails sent through Xfinity's webmail or official mail servers are automatically DKIM-signed by Comcast.


Custom Domains: If you are routing emails from a private domain through Xfinity servers, Xfinity will not sign them with your custom DKIM key. In this case, Xfinity recommends setting up SPF for your domain, though custom DKIM requires hosting your email through a different provider.


Incoming Security: Xfinity strictly checks incoming emails for DKIM, SPF, and DMARC to protect users from spam and phishing
