Have been struggling with blocked emails and getting no help from Verizon. When sending emails via Outlook, most are rejected whether we create them or just forward them. Sometimes we get a spam notice, but most of the time they just disappear. Have contacted Verizon support and they have changed the outgoing port number with no improvement. They blame the signature block we attach to emails, but removing doesn't seem to improve anything. They say we can't contact the spam people except by email, but that doesn't seem to get any response. Meanwhile, the IPs that Verizon assigns us are on the blacklist. Verizon says this has nothing to do with the problem, but I have to think that it does. Would appreciate some help!
