G Suite emails not being delivered to comcast.net addresses

Hello,

 

My cleint, Renaissance Secondary School (rensec.org) is having a problem whereby emails they send to comcast.net email addresses are not being delivered.  I worked on this with Google, and they were not able to resolve the problem because everything on their end is configured properly.  I found a forum entry (https://forums.xfinity.com/t5/Email-Web-Browsing/Gsuite-Messages-not-getting-through-to-Comcast-net/...) from another user who had the same issue, and their domain had been flagged as problematic by Comcast.  Can you please take a look at my domain to see if we've been similarly flagged?

 

Thank you in advance for your help.

Re: G Suite emails not being delivered to comcast.net addresses

Hi @RenSecIT! I'm having the same issue and it's been very frustrating trying to understand what the issue is and how to address it. I've spent numerous hours on the phone between Comcast, Google, and GoDaddy and I feel like I can't get an answer from anyone - it's like no one has heard of this issue before. How did you end up solving it? Like you, our business domain emails, managed through GSuite, aren't getting to any @comcast.net users - there are no bounce emails, no notification of any issues, just emails going missing in the ether. Thanks for any guidance! @ComcastAntiSpam - Can you help?

I would need to know the domain that you're having problems with.  If possible, sending a test message today might also help.  Thanks.

Hello! Thanks for your reply!

 

The domain is LancasterRecumbent.com. I've worked with GSuite to update DNS, DMARC, SPF records and have been sending test messages to our personal comcast.net emails accounts to see if things have self-resolved. Please let me know if you need any additional information.

Give it a try now.  It looks like there was a number of spam complaints relating to that domain.  If it's still not working, send me a PM, and we'll get it sorted out.

Hi @ComcastAntiSpam ,

 

Emails from the G-Suite domain livingonhhi.com are not sending to comcast.net. Can you rectify this issue? Thank you!

Re: G Suite emails not being delivered to comcast.net addresses

I saw your PM, and I did reply.  It should have been resolved a few hours ago I believe.

Re: G Suite emails not being delivered to comcast.net addresses

We've had many issues with sending to comcast.net addresses (stillwaterlibraryfoundation.org).  One of our consultants had a comcast.net address and it took 3-4 months to figure out that she wasn't getting the messages.  Additionally I've been having issues setting up google groups in our suite domain as one of out members has a comcast.net account and doesn't seem to get the emails.  It's not an issue with any other users e-mail addresses.

 

We dont' have a professional gsuite manager, only volunteers, but I did figure out after some searching that it's important to have SPF, DKIM, DMARC setup for the domain.  We did have SPF setup, but not DKIM or DMARC.

 

However, google's own security checklist for small businesses only recommends SPF setup to avoid having e-mails marked as spam:

https://support.google.com/a/answer/9211704?hl=en&ref_topic=7559287

 

Anyway, I setup DKIM and DMARC for our domain hoping that would fix the issue but it hasn't.  So I guess we're being blocked for some reason - could you look into why we're being blocked?  I can send from my personal comcast.net account to my e-mail at the foundation but when I reply they never make it through and don't even show up in the spam folder.

Re: G Suite emails not being delivered to comcast.net addresses

Give it a try, looks like there were a number of reports against your messages, and it caused them to be flagged as spam.

 

Generally, yes, DKIM/SPF/DMARC are all good things though, and I give you credit for adopting those.

Re: G Suite emails not being delivered to comcast.net addresses

Thank you.  It appears to be fixed now.  Is there some way to know what e-mails originally caused the issue or get any more details on why the messages ended up being blocked for everyone on comcast?  I don't believe we ever had any mass mailing sent out from any address at stillwaterlibraryfoundation.org as mailchimp still uses an old gmail account for sending.

 

Or are there steps I can take to get notified if we end up in this state again?  We have some comcast users on the foundation board and while I want everyone to start relying on google groups it would be a problem if our comcast users started not receiving any communications from those group addresses due to the whole domain being blacklisted.

Re: G Suite emails not being delivered to comcast.net addresses

It was a number of "Spam" complaints from recipients.  It doesn't always have to be mass marketing, but can be just that someone doesn't want to get the messages and doesn't use delete/unsubscribe.  If it recurs, feel free to PM my account, and we'll get it sorted out ASAP.

@ComcastAntiSpam  I have the same issue, I cannot receive emails from G-suite, can I know the reason and the solution.

Re: G Suite emails not being delivered to comcast.net addresses

You'll need to provide the domain of the missing messages before we can give that information.

Hi there, we are also having this trouble--no bounceback, and no messages in recipient spam folders either, that we can glean.

 

The domain is schlowlibrary.org--pretty sure our SPF/DKIM setup is good.

 

Could you possibly check for us @ComcastAntiSpam ?

Re: G Suite emails not being delivered to comcast.net addresses

it's not the same core reason, but I see the problem.  I've requested it be resolved, and it typically takes about 30 minutes to get to production.

Wow--thank you so much @ComcastAntiSpam for your rapid response.  Is this the best venue to resolve future issues like these then?  Also, if there's anything amiss on our end, please let me know so we can help avoid it--our library patrons get cranky when they don't get their notifications from us.

Re: G Suite emails not being delivered to comcast.net addresses

It works! Thanks so much.

It is a little worrying that I might be missing other emails due to this feature. Would it not be better to tag them as spam/junk and let the customer white list them? Thanks again for all your help.

We're seeing the same thing with our Rowing Association: @whatcomrowing.org. We use GSuite and our members who have Xfinity/Comcast email addresses aren't getting emails when they are sent to a group alias for our classes as well as emails that are sent individually. Can you help with that?

You'll need to supply at least the problematic domain so we can do some additional research.

Re: G Suite emails not being delivered to comcast.net addresses

I am also having issues with our domain (@ComcastAntiSpam  please DM/PM me for the domain, I'd prefer not to disclose it on this forum) which utilizes Gsuite for our email provider. 

 

  • I've boosted our email security to meet the standards posted by Comcast.
  • I've submitted a request to remove any IP blacklists that might exist, but I was told that we weren't on any such list. 
  • I've added a Contact record in my comcast.net account
  • I've sent an email from my comcast.net account to our domain email account to test if a reply email would at least be delivered
 
None of these troubleshooting attempts have resolved the issue. :/

@ComcastAntiSpam Hello ComcastAntiSpam, I appear to be having a similar issues. Emails from our domain oxalisportland.com are not reaching my personal Comast account or the accounts of our customers. Interestingly, we do send some emails from a mailing list (via MailChimp) -- those emails appear to make it through to Comcast, but one-off emails that we sent via G Suite do not make it. 

 

Can you please assist with this issue? I've spent hours trying to get it resolved already. Thank you for any assistance!
