I am hitting a dead wall with the support team of my email hosting provider.
The IP they assigned me was blacklisted and so sending emails to AOL.co.uk end up getting rejected. After several emails back and forth, it has been de-listed from all blacklists.
The support staff is claiming that since I have Gmail automatic forwarders set on my email accounts with them, any spam received on these accounts, is automatically forwarded to my Gmail. To Gmail, it appears as if I am sending/forwarding the spam. Thus, my IP reputation is affected. But I am merely forwarding all emails received to my Gmail inbox so I can read/write email using Gmail's features.
I have two questions: 1) Could this really be an issue? And if so, 2) Surely most people have forwarders set this way and there is a lot of spam received and ultimately forwarded? What is the correct way to do this, so your IP reputation is not affected by mere forwarding.
