Suspicious emails about the transition to Yahoo email.

I have just become aware of the planned transition to Yahoo.  I am now getting emails say that I must login through the emails and make the changes in the next few days.  These emails look suspicious, especially since I see no way to make the changes when I login to my account (and since clicking on one sent me to Korea).  How can I know if these or future emails are legit?

Needless to say, Xfinity Assistant was totally useless.

Thanks,

Ken

Check email that claims to be from Comcast/Xfinity with their Connect webmail (https://connect.xfinity.com/), and look for the XFINITY Verified Email logo. Note that anyone can insert an XFINITY Verified image in the body of an email, so it's important to note not only the presence of that image, but that it is in the correct locations:

  • proceeding the email subject line in the list of emails
  • above the subject line when the email is opened.

See https://www.xfinity.com/support/articles/comcast-verified-email for examples of valid logo placement. A logo in the body of the email does not count.

Unfortunately, AFAIK the logo is not present when you view one of their messages in an email app or program. It's only visible when you use their web email site, and only for email sent to a Comcast.net address.

Samples of recent scammer messages can be found at https://spa.xfinity.com/alerts under "Top Phishing Scams". To report a scam email follow the instructions under the "How do I report phishing email sent to or from a Comcast.net email account?" heading on https://spa.xfinity.com/help/email-abuse?faq=spam-email.

I clicked on that link and I've never seen an "Xfinity logo" next to a subject line in my life - here's a screenshot of what that site says webmail should look like, but like I said I've never seen this ever in the 30 yrs I've had Comcast email:

I just got a phishing email about switching my accounts, which I assumed was a real Xfinity email about the switch to Yahoo, although the email didn't mention Yahoo - here's what I see in webmail - note the green checkmark next to the phishing email and no Xfinity verification logo: 

I don't know if the link above to a valid Xfinity logo is old or not, but it's not accurate.

The "comcast-verified-email" article you posted the image from is somewhat out of date (they're not exactly famous for keeping their support info up-to-date). Here's what the Inbox view looks like in Firefox on my Windows 11 desktop when emails from Comcast/Xfinity are present: 

And this is what a "Verified" message looks like once opened: 

"Xfinity Verified" only applies to emails sent by Comcast/Xfinity, and since none of the 3 messages in the second image you posted are, we don't expect them have Verified logos. The green check mark does not indicate "Verified", it was a graphic added by the scammer who sent the email to make it look safe. It actually means "Danger!".

What extensions do you use in Firefox - Adblock Plus or Ublock Origin? I used Firefox ever since it branched out of Netscape, but as it became more and more like the hated-by-me Chrome GUI, I switched to Waterfox and Brave - I've used probably 5-6 different Mozilla based browsers over the last 20 or so years and have never seen anything like the screenshot you posted - I also heavily modified my browser settings and userChrome.css file, so it may be something I'm blocking from showing up. But nope, and I just disabled both ad blockers, still don't see anything remotely close to what you posted - I don't think I can even block something like that "verified" logo by modifying the css file, it's mostly used (by me at least) to get rid of useless items in my right click menu and to modify text spacing and fonts. I have 3 Yahoo accounts and 2 Gmail accounts besides my 2 Comcast accounts, frequently forward emails from one account to another, both from the webmail page and from my PC's email client Windows Mail (POP3), so you can say I've "tested" this multiple times. No need to reply unless you want to since in a few months it won't matter anyway, Comcast webmail is going away.

It's probably something that you have modified because I just downloaded Waterfox and here is what I see in my webmail:

If you've modified Brave and don't see that, either, well..... And, I know it does show up in Chrome [which I don't like, either, nor Edge].

@Again​ I never got an email saying you responded to my last post - just got a new one alerting me that someone had added a new comment to this thread then I found yours. I don't use a CSS file with Brave - you can't, at least not in the same easy way you can use a CSS file with a Firefox/Mozilla based browser - they made it so difficult it's not worth the effort, you have to create every custom modification rule one by one instead of editing one text file.  BTW, in Brave using Xfinity webmail I *did* see the verified icon next to the "Community Mailer" email alerting me to the new post here - the reason I don't see that icon in Waterfox is because I have two Comcast email addies, and the main one I use here is always open in Brave - in Waterfox I stay logged into my secondary personal email addy, so I shouldn't see the "verified" icon because Community Mailers don't go to that account.

For what it's worth, I regret enrolling voluntarily into Yahoo's e-mail system.  I usually "roll" with changes, but this one has been difficult.  First up, the format of your messages and replies is awkward.  Next, the margins on your screen cannot be moved (as far as I can tell) and there is a large, empty space to the right of your screen.  Too, ads are placed in your Inbox (that you cannot delete yourself).  You can - for $5 a month - have them removed.  I find the system very non-user friendly and could I revert back to Comcast, I'd do so in a moment!

@berkeleyboone​ I suggest you learn how to use a computer based email client like Thunderbird or Windows Mail (not the Win10 version, it stinks - I still use the email client that came with Vista PCs and POP3 the Comcast servers every 5 minutes to download new mail. I have a dozen different personal folders in WinMail to keep things organized by subject, but years ago when I was having trouble downloading emails I tried Thunderbird, easy to set up using the POP3 settings on the Xfinity website, but it was impossible to recreate those unique folders and import the correct emails into them from WinMail because it uses something called a "WindowsMail.MSMessageStore" file (a database) to store all emails - the folders I see in WinMail are sort of fake, they refer to specific emails in that file. I've used Yahoo email since it first came into existence and it's changed a lot over the years - not for the better either, because a private equity group bought Yahoo from Verizon around 2018 and started making all kinds of changes to monetize the free Yahoo email accounts. Don't know what browser or OS you use, but in Firefox you can use Adblock Plus and/or the Ublock extension to hide all of those ads you see on the Yahoo webmail page, and very little of my 16:9 monitor is filled with empty space on the right side of the main email page - see attached photo - but I use extensions in Firefox to resize website fonts and zoom settings so you may not see things the way I see them. Note: I edited this screenshot to black out personal identifying info, those are the black boxes - otherwise it's exactly what I see.

@berkeleyboone​ I too was "voluntold" to migrate to the Yahoo Mail system from Xfinity and while I am not adverse to change this one just plain [Edited: Language].  I agree with you on the reasoning and I feel like I have to do this as my Xfinity email address is embedded in so many places and I can not afford to change.  I also don't like the platform especially on a mobile device.  I shouldn't have to pay for add-free since I am being forced to do this.  Xfinity is just trying to reduce their expenses my not offering an email subsystem - but are they going to pass that savings on to it's customer?  Of course not.
