spanhous.org blocking spectrum email

[pcpete]

We have a client who we were getting a message that spamhaus.org was blocking her form sending messages via thunderbird. When we log into spectrum web mail and try and send a message we get this same error. Does this mean spectrum is blocking our client? If so this is a really unclear way for them to do things. I am guessing we need to call spectrum.

That's what I'd do. It sounds like something has had "end user error" on the part of Spectrum's admin team.

spamhause doesn't block emails per se. It's the source IP addresses and/or FQDN. Post the full email making sure to include all headers.

If they are using spectrum webmail are they blocking the whole domain of spectrum? That is what it seems like, but I an sure that is not the case.

When we were sending a test email from their spectrum web interface to a Gmail address, we got a pop-up from from spamhaus. How can spamhaus see what we are doing inside ssl encrypted email unless they are working with spectrum?

Is this client using residental service to run a business and send lots of emails to clients?

Seriously doubt they're blocking the domain. As @Porthos hints at, using a residential service, including email, to send tons of emails is inviting problems. I had a customer who did that years ago. Insisted on using his home Comcast account to send everything, including opt-in mailings. Every few months he'd start getting black listed. And that stuff just spreads, one service feeding off of another. You need more information. For instance have them send an email from their smartphone using the device carrier. And you do need to see the emails. One of the many pieces of information collected is the originating address, X-Originating-Ip:, which is the public gateway for the sending device. RBL's collect these, in turn reporting them to the IP owners who them block the traffic.

I get that. I have seen our local cable company block customers for sending out too many emails. I have never seen an email blocked with a pop-up directly inside someone's web email referencing another company blocking it.

It seems crazy that spamhaus is scanning every single email in real time and blocking them immediately as spectrum is sending them out. Then spectrum is allowing this

Obviously, spectrum is PAYING Spamhaus to monitor their network for spammers. Your client has been flagged as a spammer for mail volume.

Stolen, spoofed or real I've gotten a bunch of spam emails from Spectrum/Charter addresses lately. I forward them to abuse@charter.net and then block them. Maybe they are getting serious about the problem.

Thanks for affirming my understanding of how I think things work. Spectrum would have to be doing this with spanhaus.orgs help, physically nobody else can block the ip like that, correct? Is what is strange when I searched for spamhaus and spectrum, I only found one result. It did not seem clear that it was spectrum doing this (it has to be)
