New capabilities and functionality
Sending Domains Enhancement - To comply with industry standards, increased DKIM key length from 1024 bits to 2048 bits, significantly reducing the risk of forgery and cryptographic attacks. DKIM selectors are now generated internally for each sending domain to avoid DNS-related issues during migration. Replaced TXT-based DKIM records with CNAME-based records, simplifying setup configuration and making it convenient for the service provider to update DKIM keys without requiring changes on your part. Once CNAME-based DKIM records are verified, old TXT-based DKIM records are no longer required.
