As far as I can see, this is the first time there has been an issue reported with email from Morrisons.
In answer to your statement above, no, Virgin Media do not block specific email senders and they certainly don't block senders because they are sending you too many messages.
However, they do check all incoming emails to make sure that the mail is not coming from a known source of spam but they use international databases (also known as "blacklists) compiled by the internet security industry, they do not create their own blacklist.
The other thing they do is to use validation which checks that the sender's email address has not been spoofed (faked). In other words that email is actually from the person or organisation that appears in the "From " field in your Inbox, See here for an overview of that https://community.virginmedia.com/t5/Email/Virgin-Media-SPF-Authentication/td-p/2921597
I know it sounds simplistic, and I am sure that you have done this already, but the first thing to check is that the email address has not been blacklisted in your VM email account.
To do that, sign in to your VM email account from here https://mail.virginmedia.com and then click on he icons 1, 2, 3 and 4 as the come up.

Check that Morrisons' address does not appear there.
VM filter rules only work on emails that come into the Inbox so your filter to move any incoming Morrison's emails into the Inbox is completely redundant, in fact you are better off disabling it.
I would also check any other filter rules that you have set up. VM filters have a habit of doing the unexpected so double check that Morrisons' emails are not being affected by any others you have set up. In fact it would be a good idea to disable all the rules temporarily to see if Morrisons' emails start coming through.
If all that does not show any possible reasons for the behaviour you are seeing then the only way to troubleshoot it is for Morrisons to send you a copy of the Non Delivery Report (bounce back error) message they are receiving. That will at the very least give a big clue as to why you are not getting their emails. Unfortunately, the Customer Services agents in organisations such as Morrisons usually do not want to get involved in trouble shooting exercises. Their view is "it's your problem" although they are usually more polite than that when they fob you off. 😮
As I have explained, VM will not have created a rule to reject all emails from Morrisons.and without an example of an affected incoming email it will very difficult, if not impossible, for VM's security team to identify the reason for the behaviour you are seeing and to resolve the issue.
By the way, if you can get a copy of the error message Morrisons are receiving, anonymise your address by removing the part before the "@" symbol before you post it here. 😉
Finally, I will just say that I was involved in trying to resolve a similar problem on this forum where the poster was not receiving newsletters from their golf club but all other emails from the club were coming through fine. To cut a very long story short we eventually proved that the reason was that the golf club had an incorrect email address in the distribution list they used to send out newsletters. Sometimes the answer is very simple one.
