My local registrar allows registration of domains ending with
.com.uy and has recently started offering
.uy domains (freely offering
.uy addresses to their existing

Email is currently working nicely at
@domain.uy on my server, which currently has SPF, DKIM and DMARC setup. A SSL cert has been setup for that and so far exim4 is working flawlessly. However, I would like users to be able to receive emails on their inbox regardless of whether emails are being sent to the
.com.uy or the
.uy version. Bob, whose email address is

I have been reading about Address Rewriting not because I've been suggested to but because I thought it could work. However, I haven't changed anything yet because I would like to get some opinions on that. I also have read this but did not really understand it.
I would like this to be server side(not requiring configuration on the end user), server wide (i.e. not requiring per-user configuration) and clean enough to avoid any possible problems with SPAM filters.
I have root SSH access to the server and full control on its DNS records.
Thanks in advance

domain.uy but is currently failing with remote emails.
