Our statuspage account was set up many years ago, hence, I dont have the tribal knowledge behind this. We are using custom domain to send notices to our clients. Under the DNS configuration for our page, I do see 3 CNAMEs (all for sendgrid) and one DKIM TXT record. Our security team is advising us to upgrade the key associated w/ this TXT record (from 1024 to 2048).

After reading a few docs, I learned Atlassian is using 2048 if we utilize the CNAME values. With that, would i be able to delete the DKIM value from our DNS server? There's only one option for DKIM I see, i wasnt sure if i need to replace it for DKIM to work properly.
