Warning: DKIM key shorter than 2048 bits
selector2 (1024-bit), k1 (1024-bit), s2 (1024-bit) uses an RSA key below 2048 bits. Short keys can be factored and some receivers treat them as weak. Rotate to a 2048-bit key at your sending provider.
Pass: DKIM key published

AlignmentDoes it match your From?SPF alignment is unknownInfo

Info: SPF alignment is unknown
The SPF record of dynatrace.com authorizes no sender (no +ip4, +ip6, +a, +mx, +exists or +ptr term, include of a record that has one, or +all before all), so SPF never passes and cannot align. That is correct for a domain that sends no mail; otherwise DMARC depends on DKIM alone.
