missed-spam@comcast.net mailbox full

I regularly forward spam email to the Comcast Missed Spam mailbox, and it does seem to help cut down om the spam I get.

Unfortunately, for the last week every message I send there is undeliverable as the mailbox is full. What's up with that!

This is what I get:

      This is an automatically generated Delivery Status Notification.     

 

Delivery to the following recipients failed permanently:

 

   * missed-spam@comcast.net

 

Reason: recipient mailbox full

@user_tr50a  thanks for the report. 

I found the systems generating that error, and I'm working to get this resolved ASAP.  

FWIW, the best way to report spam in webmail is to use the spam button at the top.  In a third party client via IMAP, moving the message to the spam folder should do the same.

I would just start deleting it.

tremblay50 Thanks for reaching out about the error message for spam. Since it started have you emptied the spam folder completly? If you are unsure how to do so:
  1. Right-click the Menu button next to the Spam folder.
  2. Select Empty Spam to erase all spam emails.

It's not my spam folder that is full, it is the Comcast Missed Spam inbox that is full, for reporting spam emails.

I empty my spam folder daily.

tremblay50 To confirm, you are referring to the folder for reporting spam emails is now full correct?

No, the Comcast mailbox that receives spam email reports is full:

 This is an automatically generated Delivery Status Notification.     

 

Delivery to the following recipients failed permanently:

 

   * missed-spam@comcast.net

 

Reason: recipient mailbox full

My apologies for the misunderstanding, @tremblay50. I just tried forwarding a test message to the missed-spam inbox, but I did not get an immediate bounce back, at least not from my Comcast email address. Do those normally come back to you right away, or does it take a few minutes? Can you please try logging in to the webmail page at https://xfinity.com/email and tell me if the spam/phishing icon gives you a similar error or bounce back?

It comes back almost immediately.

I have started sending it to both the report-spam and abuse addresses noted in one of the replies, only the report-spam mailbox comes back as full.

Folder?  That's an email address that is documented here:

https://spa.xfinity.com/help/email-abuse?faq=report-spam-email

But with xfinity getting out of email, I suspect whoever used to look at that has been reassigned to something else.

I have always sent my spam messages as attachments (per their request) to missed-spam@comcast.net. for several years.

So what do we do about spam now?  Ditch Xfinity completely?

Just start deleting it.

If you go here https://spa.xfinity.com/help/email-abuse and try clicking on the Email Abuse icon you'll notice that it no longer works.  Chances are, with the migration, that Inbox has been closed, but I do not know that for certain at this point.  I'll need to make an inquiry to find out.

It only appears that way because your link already specifies that you are want to know about "Email Abuse". If you visit https://spa.xfinity.com/help/ I believe you'll see that all five of those tiles are still active. If you link directly to one of them (https://spa.xfinity.com/help/advanced-security
https://spa.xfinity.com/help/email-abusehttps://spa.xfinity.com/help/identity-thefthttps://spa.xfinity.com/help/network-abuse, https://spa.xfinity.com/help/postmaster) its tile appears inactive because you're already on the page it links to. 

It is IMHO an odd design decision, but there we are.

Two different reps have told me to switch from missed-spam@comcast,net  to abuse@comcast.net.  As before, forward as attachment. That seems to work.

@user_izfl75​ That is not correct IMO. 

When you forward a message (not as an attachment) it loses critical information.   If you're using webmail, use the "spam" button at the top, it will do the correct thing.  If you're using a third-party client (Outlook, Thunderbird, Mac Mail, etc), move the message to the spam folder, it will do the correct thing.
