Anyone using cPanel or Plesk with e-mail alias subaddressing?

Can someone using e-mail from their cPanel and/or Plesk do me a favour?

I need to know if I can use subaddressing for e-mails aliases

Like, main inbox:

And then create an alias e-mail: ->

And people can e-mail to this: (this is what needs to be tested)

I tested with DirectAdmin and it didn't work for e-mail aliases, it only worked on main inbox.

Spent hours moving e-mails and then noticed this situation, had to move everything back again :melting_face:

Yes in Plesk you can create as many aliases as you want and forward them.

Just don’t use my email address :slight_smile:

Can you explain what you are trying to do here? Where would someone get this email from if it doesn't really exsist?

From ChatGPT:

Yes, both cPanel and Plesk typically support email subaddressing, also known as plus-addressing. This allows you to create dynamic email addresses using a base email address and appending a plus sign followed by additional text (e.g., These emails are typically delivered to the main email address (, but the subaddressing helps you filter and organize incoming emails based on the appended text.

I have accounts on two different providers that use cPanel. I will see if I can do some digging. First I ever hear of doing such a thing.

It's a technique called subaddressing, an e-mail going to would in fact go to

If you have a GMail account you can test it by sending an e-mail to yourself.

This is often used by help desk softwares, to keep track of "tickets" in alternative of the ticket number being in the title.

So there's a general inbox for the helpdesk software, like:

And then there are many departments:

And when people send replies, they're often replying to:

The problem is all of those are aliases of the main inbox, and in DirectAdmin subaddressing doesn't work for aliases...

Thanks in advance! Any digging is appreciated.

Alright, setting up an email filter was pretty straight forward in cPanel. I was able to set up a filter for: which does in fact redirect to (also tested redirecting to

At first it didn't seem like it was working but the emails were in fact going to my Spam folder. Is that what you are trying to accomplish?

Are you using Global Email Filters or just Email Filters in cPanel?

They're not supposed to go to the spam folder :frowning:

I didn't know about e-mail filters. I was thinking about this option:

Looks like cPanel doesn't seem to have the concept of "e-mail alias", right?

Also, the goal is you don't hardcode the "+123" part, that should be done magically

I think cPanel calls them Email Filters ...... the Forwarders is just for directing a valid email address to another valid email address.

For example, I have all my emails directly forwarded to

Hmmm, that should still be possible. Just filter by To --> Contains ---> sales+ then anything withe the sales+ in the to address will be forwarded.

How is the number being generated?

Thanks, the number is random.

If you delete the filter, are you able to send an e-mail to and receive it on (basically, just using the forwarder option; don't create a specific rule for +123, let it just as it was)

You mean remove the filter and send to brad+123?

Yes, assume your regular config before you started this experiment, since you have a forwarding

So I removed the filter completely and sent to and it came through successfully (to the Spam folder again but I am sure I could set up a local email rule to send them to inbox.)

That sounds promising! Thanks for your time! It's enough help for now

No problem, I owe ya a few :wink:

On Plesk subaddressing doesn't seem to work

Doesn't work on my PLESK Obsidian either, there's a feature request here:

With Plesk it is an option for the mail server that you have to enable first:

In Tools & Settings / Mail Server Settings:


What version is that George? Im not seeing that on Windows/Obsidian 18.0.62

From the changelog sounds it's Linux only, good catch

No experience with Cpanel or Plesk but I set up email forwarding in cloudflare for free Email Routing | Easily create addresses and route emails

Maybe useful?
