how to stop spam arriving for one email alias address - e.g. alias@myusername.plus.com

[#1]

Hello, I couldn't find anything in the help to anwser this...

I make wide use of email aliases (if i have the terminology correct?) , i.e. me@myusername.plus.com, or thedog@myusername.plus.com, completegobbledegook@myusername.plus.com e.t.c.

I am getting spam emails sent to one of them - shop@myusername.plus.com. 

The company "shop" itself is no longer in business

They are being sent from lots of different email addresses

some are getting antivirus warnings if I just delete them which is concerning!

I can do a "block sender" for these individually which is doable but very tedious

Q) Is there any way for Plusnet to block emails sent to a specific email alias?

or something I can do in settings in outlook? I'm using Outlook 2019

Thanks for taking a look

With Outlook you should be able to setup up a rule to move defined 'To' emails to a defined folder, right click an email in the inbox. In the past I have defined Trash/Bin

There is this guide https://www.plus.net/help/email-guides/spam-protection-guide/ in the help section.

How about just deleting the alias, do you need it at all ?

You could edit the forwarder to a webmail only box and just ignore it and clean out once a year

@bladerunnerplus This

If you only used this alias for that one shop which has now gone out of business then just delete the alias.

My think is @bladerunnerplus has setup 'Catch All' in 'Manage My Mail' control panel.

This makes any email addressed to  @accountname.plus.com to be move to a specific Mail Inbox.

This is handy to collect email for many addresses, without needing to add each address individually.

To follow on from that and address the problem of a catch all as @Dan_the_Van says

You can stop all mail to that alias as follows:

Delete the alias 

Create a redirect for that address and set the destination to blackhole

I vaguely recall an option to set an address as  :blackhole:  and that 'forwarder' took precedence over a catch-all which is last in the queue of actions.

Not sure if it still works, or given Greenby is imminent would still work then

I think the order goes:

Is it for a mailbox address ?  Y - send it there

N>

Is it for a forwarder address ?  Y - send it there

N>

Is it for :blackhole: ? - Y - delete

N>

Is there a catch-all ? - Y - Send it there

N>

Delete anyway (or bounce ??)

Feel free to correct if that is not right

It works like this...

1. Is the mailbox-name@ specified explicitly in the email configuration?
   1. If a mailbox - deliver to mail box
   2. If an alias - deliver to alias target
   3. If a redirect - redirect to redirection address - that can be blackhole@abuse.plus.com
2. Is CATCHALL enabled?
   1. Yes - deliver to the CATCH ALL mailbox
   2. No - reject delivery with address does not exist NDR

You have wisely used distinct email addresses for each <shop> you have done business with (I do the same), therefore...

1. If you have an explicit mailbox or alias for mailbox-name@ - delete it
2. Create a redirect for mailbox-name@ to blackhole@abuse.plus.com
