Z-Man Posted April 4 Share Posted April 4 We use Hostgator, which uses SpamCop. We have whitelisted the domains, but since SpamCop Blocks are at least partially based on IP, whitelisting is ineffective. We are losing business because of this. And we can't prevent our clients from using Microsoft. Quote Link to comment Share on other sites More sharing options...

If you have reports or errors from SC can you post this info here to hopefully help you thanks? Have you reported your concerns to MS and hostgator?

Whitelisting a domain should bypass the check for spamming IPs. Yes, SCBL is a dynamic list of IP addresses that are currently spamming. You should NOT have to get you clients to change ISP. You should get Hostgator to configure their mail server so that the whitelist of your client's domain bypasses the filtering of incoming email based on a block list.

Thanks, I agree with what you said 100%. I have been discussing with Hostgator throughout this. It is so frustrating. Quote Link to comment Share on other sites More sharing options...

TonyL Posted June 5 Share Posted June 5 (edited) I have been encountering the same problem when sending from 365 based accounts. Getting bounceback errors due to Spamcop IP Block. So far I'm only having trouble emailing one particular recipient. Having said that, after trying to send the same email about 3 times, eventually it looks to have gone through. One of our customers is having the same problem. They've sent me a screenshot of the error that their customer is getting, and its the same spamcop IP block error. Figured I might as well post here so other people can at least be reassured its not just them! Hopefully it gets resolved soon. Ironic that my forum registration/activate account emails ended up in my junk folder (365 hosted) 40.107.107.92, 40.107.107.97, 40.107.108.122 were the IPs being referenced in my bounceback errors Edited June 5 by TonyL Quote Link to comment Share on other sites More sharing options...

These email addresses only go to blocklists (ScamCop Blocklist is just one of them, most if not all major email servers have their own and don't give a bounce) SpamCop will only block if the poisoned emails hit a certain volume, for major servers like Microsoft's it would be a lot, when the spam stops hitting blocklist after 24 hours it stops blocking. Marketing needs to be done professionally not by naïve marketing beginners, who use a mailing list/s created by Web-spider/web-crawler bots, who scape email address from the internet, these are the main source of "poisoned" email addresses and are there to feed blocklists. Mail Chimp seem to have reasonable advice on how to set up marketing/church/Nigerian/etc mail lists. https://mailchimp.com/help/about-double-opt-in/ Quote Link to comment Share on other sites More sharing options...

MS should fix their issues ASAP. This is very frustrating. Quote Link to comment Share on other sites More sharing options...

MS should fix their issues ASAP. This is very frustrating. If not in to-hard basket you could maybe use a whitelist for known sender email addresses. If configured correctly it would bypass any and all blocklists you use. This means that a email receiver, upon requesting, get email from even Microsoft. Maybe you be able to set the SpamCop Blocklist (actually a spam radar, when spam stops for 24 hours it releases that IP) Anyhow set to a "retry queue" for 24 hours with limit of 3 retries? Better if Microsoft advise their 360 users to ask those on their list to reply, those that don't they need to be removed from their list.
