I've received a direct reply with a few tips, appreciate it

Debug logging hasn't shown anything, and monitoring doesn't show any 
issues with resource availability (CPU / RAM / disk) that could be 
impacting this. I've updated to php 8.3.21 from 8.3.20 and will monitor.

Another reason for this update - I've realized my SPF hard fail setting 
may have caused some mailing list receivers to not get my initial 
message. It's now softfail based on recommendations here:
