Why is my server on a blacklist It's not uncommon for a mail IP address to end up on a public blacklist, especially on a shared server. It could be due to overall volume of mail coming from that server, or messages seem to have characteristics of spam in them. Another common cause is email forwarders.

One of my domain is using https://www.cloudns.net/ as DNS server, they also offer email forward, so I need to setup my MX to
to use the email forwarding.
Everything is perfect except the
mailforward1.cloudns.net
and 2 as well, are heavily listed in many popular blacklist. I can understand that since they just forward email and not care about who sent it or what content it is, so it will have bad reputation. And amazingly, the blacklist of the mentioned domain/IP does not effect I receive the forward emails.What I wanna ask here, is not I will use these smtp server to send email (I cannot anyway, since they are not for public to send email).
My question is: for the emails I sent, which contains the domain that has above smtp server as MX, will the blacklist of the MX servers cause my email has higher spam score or cause no-delivery.
If answer is yes, the domain in the email will effect the delivery, then what kind of remedy do you suggest except not use the email forwarding service.

Typically, someone getting mail from an SMTP relay will only check that relay's reputation against their relay blacklist - the reputation of systems present in the
MX
records for that domain should not impact the spam score. So, you should be fine.However, that's not a guarantee - someone receiving a message can build a spam score however they'd like, and I've seen crazier ideas implemented in SMTP filters.
