A quick look at the DNS for acm.org shows this TXT RR for SPF

"v=spf1 include:_spf.acm_org._d.easydmarc.pro ~all"

this for DMARC

"v=DMARC1;p=reject;rua=mailto:9adb8cf49b@rua.easydmarc.us;ruf=mailto:9adb8cf49b@ruf.easydmarc.us;fo=1"

easydmarc.pro sound like a service for email authentication

anyhow that p=reject means that email that doesn't pass SPF and DKIM is likely to be rejected or quarantined (treated as spam) by receivers.

Maybe your acm.org service is misconfigured (perhaps due to easydmarc) and needs to keep up with the new reality of the email landscape where companies like Google and Yahoo! have recently become stricter.

The above depends on what the domain name of the forwarded mail is. If it's not acm.org then it probably doesn't apply.

Reminds me of ARC (RFC 8617) which is designed for forwarding issues but takes time to get up to speed due to relying on reputation.
