I guess all HTTP links were added by sender's MUA. These clients creating
links from anything separated by dots are quite annoying.
reputation issues can be side effect of this, but having A record is a good
idea in such cases.
But this may be related to the drop in reputation of Amazon SES IP
Space. Do they offer a dedicated outgoing IP Address that you can
try? It also helps reduce any chance of forgeries.. Eg, smaller SPF
footprint, that could have poisoned your reputation.
DKIM should help as well or even better.
_domainkey.newsletter.syniumsoftware.com produces NXDOMAIN which means
domain keys don't exist.
