Send mail as alias

Hey MiaB users,

I have been searching around a bit, and haven’t found any fix for this.

I have 2 domains, and
My email is
I made a domain alias for, to forward all the mail to
So if I mail to, it goes to

Now I am logged in to Roundcube as, I made a new identity, and filled in So now when I send mail with Roundcube, i can select either or

When I select as sender, I get this error :

SMTP Error (553): Failed to add recipient “recipient@domain.nll” (5.7.1 Sender address rejected: not owned by user

How can I solve this? (Is there any way to solve this?)

You will need to create an alias for the particular email address. That will let you send as that address.

Domain alias + Alias for that address will both work at the same time? Won’t it bug out?

No the alias will take precedence.
