Gmail has far more users than Xfinity Connect. So, tons are reporting spam and training Gmail's spam filters, which is why a lot of that stuff goes to spam and you don't see it. But, what one person sees as spam, another might not.
Your are right about the number of users, but not the training statement. These Spam items are all:
1)using different email addresses that are created just for that burst of Spam
2) using imbedded HTML links with domains that have been very recently created and redirect to another site - this is called link obfuscation.
It takes some really good programming analysis to identfy these. No matter of training in their present system is going to eliminate or identify much spam - it takes some logic that is more than repeat pattern analysis. They need to get into the contents and start scanning the raw source and look for inconsistencies like ) faked original sender email address, HTML contents that have recenty been registered less than a day or two. And any number of other things that the experts at Google and Microsoft do to keep their stuff clean.
I use MS Outlook as a client to get my Comcast email. I am always amazed how the simple Outlook desktop client will identify SPAM that Comcasts lets pass thru. Comcast just isn't putting the resources into their email system to make it better, remember its free and not a revenue center for them - at least as far as I can see.

Are you still receiving a lot of SPAM? Have you looked at the internals of the email, ie the header and HMTL links in the body. If you do, you may find that many, if not all, contain HTML redirect links that are hosted by Cloudfare.com. Here is a response I sent to Comcast after their response of my last report. Basically they are blowing me off. Suggest to others to try getting more proactive and report directly to Comcast if they find the same. Tired of the same SPAM everyday that Comcast could catch upfront.
-----------------------------------------------------------------------------------------------------------------
I am responding to your resolution below. I have hundreds of emails that have unknown senders and hosted links by Cloudfare.Com. Below is an analysis of the key contents of one of them – virtually all others (hundreds/thousands) have the same structure. Something needs to be done
1)Why do you allow forged senders to enter the email system

Looks like a forgery
2)Why do you continue to allow emails with Cloudfare hosted links to enter the system – it seems to me that each user should have the option to exclude these.

Something needs to be done to prevent these email types from propagating thru your system – allowing there entry and passage only encourages this inappropriate use of the email system.

>My filters trap about 4-5 of them, Comcast's spam filter traps about 2-3, and the rest fall through the cracks to my Inbox. My question is ... how does Comcast's spam filtering interfere with my defined filters?<
I'm pretty sure Comcasts SPAM filter processes before User Filters. So they only interfere in the sense if they catch something you wanted to have passed thru for subsequent processing. I wish User Filters were first, thus User Filters could be used to help avoid the False Positives that sometimes originate from the Comcast Spam filter. Because of this I keep the Comcast Spam filter turned off and rely on my User Filters.

It would be really easy if they would allow their User Defined Spam filters to run before their general purpose one. Then you could direct the addresses you have directly to the Inbox. But unfortunately their whole Spam solution is not well designed.

I am also a 30 year Comcast customer. I'll add my experience. Since Comcast does NOTHING, I have turned off spam filtering because it interferes with filters. And, I have been adding new filters almost every day. I currently have about 50, but I have virtually stopped spam. I still get one or two a week. I ignore the sender email address entirely because they are either stolen or made up and they change. I enter the Sender/Subject, examples: Silver-Singles, zippy loan, Roofing Survey, Wells Fargo, ZenDeals, crepe erase, and then _Crepe_Erase- when they changed it, lyft, linkedin, Evite, MemberSurvey-Customer Satisfaction, etc... Then I direct them to the Spam folder. If I'm convinced that it is working correctly, I change that to Discard so that I never see them and the spam folder doesn't get too full too soon. You can't kill 'em all. Good luck.<
Thats exactly what I do also. I have found this much more effective than their filter - as you said turn their filter off because its just interferes and also gets more false positives than good ones.

Flyboy2: Hoping you can help me as I'm learning as I go.
For example, I see the following in the View Source:
Return-Path: <bounce-mc.us7_20797027.207073-mpalmer28=comcast.net@mail61.atl31.mcdlv.net>
Wondering if the following filter rule will work:
Conditions
Header Name: Return-Path
Contains: mail61.atl31.mcdlv.net
Actions
Move to folder: Spam
A bunch of spam has this same Return-Path, but a batch of other spam has a totally different Return-Path. It's almost as if when I set the filter, they figure out a new way in!
That filter will definitely catch the ones with a Return-Path matching your contains. As you mention if they change the addresses you end up chasing your tail. Look at the other header fields of the ones you are getting (I ignore Received, too many and complicated) and see if there is something in common. For example one I have had some success with was header User-Agent:
User-Agent: Mozilla/7.10 (X11; Linux i686; rv:39.1322) Gecko/201100103 Thunderbird/39.101.
Filter is User-Agent contains Mozilla, contains Linux, contains Gecko
None of my good email has this construct and I regularly filter a bunch using this one. Your situation and mileage may vary. Look for headers in common and try to use those rather than email addresses. Also note, you may find that a given filter will catch a lot of Spam but also traps something you want. The way arround this is to add "does not contain" email address of good email. Hope this helps.

We have 5 comcast accounts and all are being infiltrated with spam - at least 15-20 per day per account! I've had to set filters on each one. As soon as I've set the rules (I use "contain any"), the spammers send from a different email address (including .com and .edu). I'm at a loss as what to do. For my minor children, I've set rules about no emails regarding "CBD, Keto, Harder Longer, limp, etc." but those are still making their way in. It's obnoxious.
Does anyone know if I can disable an account (but keep old emails)? I was thinking of disabling for a week to see if these spam emails stop.
You can probably move all the emails into a folder. Then delete one of the emails and create a new one - then move all the stuff from the folder to the new one and then delete the rest. But before you do that consider this.
Using Sender/From to eliminate Spam is not very effective for the reason you stated above. Its takes a bit more effort to create effective filters. Spend some time and examine the Spam you are receiving - use the View Source capability and see if you can find a common item in the Header of the Spams. Look at all the Header fields, Return-Path and others. Is there a common item in those. If so use a filter to catch those. Sometimes this will also cause good emails to be caught - if that is the case you can add a condition in the filter to ignore email addresses that should not be caught. A lot of work.

>I only got one spam today, and filtered it using the above solution. The emails still don't go to my spam folder, as requested, so I will keep working on that.<
If your filter is instructed to move it to SPAM folder how do you know that filter is working if it does not go to SPAM? If the spam item is showing up in the Inbox the filter probably is not working if the filter action is to move it to SPAM. To test my filters I create a separate folder named with something that will identify the filter I want to associate with it. Then I have the filter move a copy of the email to that folder as well as the SPAM folder. If it shows up in my custom folder that proves that the filter is working. Later when I have debugged the filter I remove the action to move it to the custom folder and just let it be moved to SPAM. Note: if you have the Comcast Spam filtering turned on it will process and may move items to SPAM before your custom filters - this can be an area of confusion.

From a post above >I notice the spammers rarely use ".com" or ".net," but I found a couple and don't want to filter them. We may be defenseless against those, still.<
That is an excellent observation and I will share a Filter I have to stop many of these, you need to adjust this logic based on your needs, especially if you receive emails from foreign entities. The filter I am using is like this:
Header: Sender/From
does not contain : .com
does not contain: .net
does not contain .edu
Just add every domain qualifier you use to the does not contain list, others like .gov and any foreign domains you use. Have the filter move them to your SPAM filter and track it for awhile to make sure its working like you expect.

>I've added the common domains to filter the massive spam I've been getting over the past couple of months and it's done very little to help. I continue to get spam from the domains that I have filtered. I started with rejecting the emails but that didn't work, so now filtered to have them moved to my spam folder. Even that hasn't helped. I manually move them to my spam box, but the system hasn't learned which ones to automatically move. Any suggestions?
You know that filtering will not stop the sender from sending the email. Its like someone knows your phone number, they can call it till you change it. The purpose of the filter is to redirect unwanted emails automatically to another location, like the SPAM folder. Also Spammers constantly change the email address so filtering by domain is usually not a good solution for a real spammer, it works best to get rid of email lists you are on, but that's usually not spam. So question a couple of questions:
1) For the domains that you are filtering is the filter working? what action is the filtering performing? If you believe it should work post a copy of the filter here for others to look at.
2) Does the spam you are trying to eliminate always use same domain within the email address?

Not sure I understand your response? But the method posted above will not prevent the Spammer from sending the email, once someone knows your email address there is no way to prevent them from using it.
The above method is a way to filter (intercept) the messsage and route it to your Spam folder and keep it out of your Inbox. Does this help? Note you can post a copy of the email, include header that you are trying to get rid of and perhaps we can suggest a filter? Best way to do this is to use the View Source option and copy it into a forum response.

You may have the SPAM filter turned on but for 90% of SPAM like you describe it will not catch them, nor will it learn about them. Why? Because if you exam the SPAM's you are receiving you will most likely find that the From sender is a different valid email address on each one - even if its a repeat subject from the day before. Because the spammers are impersonating what appears to be valid email addresses I believe that the Comcast SPAM filter does not have the level of sophistication to sort thru them. If you have the time and energy you can analize what you are receiving and create a custom filter to weed out the majority of them.

I have the Comcast SPAM filter turned off. It is very unreliable and does not seem to operate in a predictable manner. Too say the least SPAM filtering is not Comcasts strong suit. Turn the SPAM filter off and then create your own custom filters using the capability they offer. At the least you will then know what is and is not being filtered. If you use their general purpose filter you will be required to regularly check the SPAM folder to ensure that something you want didn't get caught. This is particularly a problem (and super annoying) for people that use some other email client and do not regularly login to Web Mail where the SPAM folder resides.

I also get an overwhelming number of spam mails from junkmailfilter.com that consistently come to my inbox and not my spam folder. I set up a filter to block emails from this domain, and it blocked ALL my incoming emails. After hours spent with varying levels of comcast help, they deleted all my filters and I started recieving emails in my inbox again. Unfortunately, they were lost in the 50 or so emails I get from junkmailfilter.com every day. I set up a filter to send emails from junkmailfilter.com to my spam folder, and now every single email I get is going to my spam folder. Somehow this domain seems to be hijacking all my emails. Do you have any suggestions?
OK - here is how I do it. Using Comcast Web Mail:
1) create a customer folder, folder name will be junkmailfilter
2) look at email header of one of these emails and verify that the From field in the header contains: junkmailfilter.com
3) create a customer filter like this
> Rulename: junkmailfilter
>Add condition Header, Name is "From", then change to "Contains", in the open field enter " junkmailfilter.com"
>Add Action, Move to Folder junkmailfilter
>Add Action, Move to SPAM (maybe be called Junk in the filter setup) folder
When I setup a new filter I always have the output directed both to the SPAM folder and a custom folder that iis named so I know it is coming from a specific filter. this does two things 1)lets you see if the filter is work and what is caught, and 2) if its not right you still have a copy of the email. Once you are sure that the filter is working OK you can go back in and remove the command to move it to the custom folder.

Check your spam filters - when you marked it, it may have added a user spam filter to your account. Go to the location in your account where user created spam filters reside and see if it got in there. If you dont know how to do that, call tech support and have them look.
