Alias setup in Gmail for forwarded Email


New Member

Long-time customer, first-time poster.

I can normally work things out for myself, but this issue has been stumped.

Here's my setup, I have no mailboxes set up on our Knownhost VPS but do have over a hundred forwarder email addresses.

What I want to do is set up an alias on my Google Workspace account, to send Email as one of the forwarded addresses.

My question is what do I input the Email SMTP server, username, and password on Gmail? Obviously, there's no password as it's a forwarding Email and not a mailbox, is there a default username and password I could use on what I assume to be I get ping responses on mail, pop3, and

Thanks for any advice you could give me to help get this Gmail alias setup if at all possible without a mailbox on our VPS.
