Bad Providers Blocking Good Email – False Positive Spam Blocks

Bad Providers Blocking Good Email – False Positive Spam Blocks

Email Service Providers

Service providers blocking good email is worse than unwanted spam. Businesses can’t function.
Poor automated spam traps with zero support to report “false positive” ip blocks.

Good email returned by local ISP? Sadly  the only way get your ip address or domain unblocked is customer complaint through account holder.

Like what the heck man, my server ip and domain is not black-listed…!!!

Internet Service Providers ISP’s like SuddenLink & Optimum won’t have a clue when you call in as a web email hosting company. About all that can be done is to send return email header via Gmail with a possible explanation of return. i.e. My server was compromised or false spam complaint or positive!

Another option might be to contact ip address owner or upstream provider to see if they can get local ISP to unblock. Last resort change outgoing SMTP ip address on server in mailips file.

550 5.7.0 Your mail from 74.208.129.213 was rejected. There are too many DNSBL-listed hosts in the /24 network with this IP. The network operator controlling the /24 must secure all compromised/spamming hosts for this block to go away automatically.

Good intelligent providers like Microsoft & Google are white listed everywhere for a couple reasons.
Tons of good email would get rejected. Superior extremely intelligent spam filters smart enough not to block good mail.
You might find some good mail in your never rejected junk mail folder!
