Outgoing emails being rejected
Would it be possible for someone to check our DNS settings to make sure they are correct? Thank you! We are receiving this message lately:

Hello,
Yes, we updated your records back in April.
Sometimes, on shared hosting where many customers use the same email servers, they get detected as contributing to spam and unnecessarily get blacklisted by a few recipient email servers and RBLs. We do have a system in place that monitors our mailout server IPs for their reputation at RBLs that sends out reports periodically. Our Network Operations team rotates the blocked IPs automatically and that should resolve any blocks our servers may have, given time. We do recommend trying to resend the bounced emails.
Additionally, we have already informed our engineering team regarding this issue and our engineers are working towards a fix on increasing the reputation. I'm afraid we do not have an ETA on this. We appreciate your patience while we resolve this issue.
