Sky is blocking my email server

msmawson24 — Wed, 20 Mar 2024 15:13:28 GMT

My email/website provider has changed something and now I cant access my work email and it blocks their website too. I know it is Sky because when I disable Wifi on my phone it loads thier website on phone on 4G but blocks it on Wifi. Im on an Apple Mac and dont have McAfee or anything like that installed. Can anyone help?

Sounds like you web/email host has a spam blacklist on a serles of ip addresses that happen to include yours due to perceived spamming by another of their customers. This will filter down to your own ip address with sky. A short term and sometimes temporary solution is to force a change in your own public ip address

Hi, thanks but I dont think it is that as their website does not load unless its with 4G on my phone so it is definitely their domain that is blocked and not my IP address to them. Ive added it to the 'allowed' bit on Sky Shield, even though it wasnt on and its made no diffeence.

Your Sky broadband's public IP is completely different to your mobile phone providers 4G public IP so it certainly could be that your Sky Broadband IP is blocked. You and unplug your hub for 30-60mins to get a new public IP.

Additonally exceptions don't always work on Sky SHield so I would disable it outright to see if that is the issue.

Thank you I will try this. Will changing the IP affect anything else in the house like the Ring doorbell or will it affect the WiFi login?

@msmawson24

The true fix is to contact your web and email hosting company and ask for your email to be whitelisted they may not know what you're on about but be persirtant and ask to go thru to the blacklist dept

Other than that temporarily disabling the connection will not affect anything

Its an small company, they say they dont have anything on their block list and when they set my email up at their end it works OK. Plus nothing changed at my end but they updated their servers and asked me to change the host name but it just doesnt work, the only thing to work is if I go to the webmail on 4G on my phone

By the way log onto your hub and go to the maintenance tab and sign in with

Username admin

Pass word sky or wifi password

Then at the bottom of the maintenance page click connection and disable for a 10-20 minutes before enabling the connection

If you don't mind what is your domain name ?

Re: Sky is blocking my email server

msmawson24 — Thu, 21 Mar 2024 12:10:35 GMT

How do I log into the hub? I cant find any info in my account.

The hosts website is www.purpleprince.co.uk Thats who hosts my email and website. My website is fine, its theirs that I cant access my webmail, email or even their website except on my phone

@msmawson24

Changing your public IP wont affect anything, your already on a randomly changing IP anyway as Sky does not provide static public IPs.

To login to youe sky hub go to 192.168.0.1 in a web browser. Your username is admin & password is the default WiFi password printed on the hub.

With no dmarc policy enabled (quarantine/reject) on the own domain i don't know if that itself filters down to your own email but apparently can have a cumultive affect seperate to spam blacklisting

If they're still adamant its not them them the changing public ip address would be the only other option. Isp's themselves are only a small link the the chain of blacklisting so i doubt its not just a sky issue

This is the tool i use

https://mxtoolbox.com/

Enter you own domain name and report anything similar back to us

Re: Sky is blocking my email server

msmawson24 — Thu, 21 Mar 2024 12:51:03 GMT

@cookiemonsteruk

it comes up with the same server as theirs:

No DMARC Record found
DMARC Quarantine/Reject policy not enabled
DNS Record found

I can still acess my website though, thats fine

@mae-3 i have asked you before but can't remember what you said re dmarc not been enabled. Can it have similar effect as a black list 👍

Re: Sky is blocking my email server

mae-3 — Thu, 21 Mar 2024 13:44:16 GMT

@cookiemonsteruk

Yes, DMARC can act as a blacklist on Google soon, and everyone else later...

@msmawson24

See @mae-3 response. @mae-3 who is responsible for setting the reject details the domain owner or the web host ? Thanks @mae-3 👍

@cookiemonsteruk

DMARC relies on Webhost and a signed DMARC signature on the domain that holds the certificate which is encoded in the DNS system with a public key.

@cookiemonsteruk

The host says :

"No dmarc will only apply to sending so it won't be that, hundreds of other customers are connected and it's working fine. It must be an issue at your end connectivity wise. We don't block any ips/subnets at all."

I spoke to Sky, they removed the Sky Shield, but it didnt really do much.

I did however delete my email account, switch on my EE 4G hotspot and add my email account on my computer using new settings which it accepted. Of course as soon as I switch back to Wifi it goes off again but at least its a workaround. Ive done this on my phone, laptop and computer and they all accepted new settings so thats something.

I think I need to find a new webhost!
