As suggested previously in this list I'd like to set up alias for all "existing" mail accounts to avoid mail for invalid accounts to be accepted (and later bounced by the primary mail server).

I tried it with:

user1@domain1 -> user1->domain1

but this didn't work.

That doesn't look like a line from an alias file.

To prevent looping, you'll want to use the hostname of your primary MX, rather than the domain name in the alias destination. Naturally, the primary MX will need to consider its hostname a "local" domain. If your primary mx is "mx1.domain1", then the alias should look like:

user1@domain1: user1@mx1.domain1

There should be no MX records in DNS for "mx1.domain1".
