There are two parts to this requirement.  DNS does not control the e-mail address that is offered to the SMTP (e-mail) server, so you need to make sure that the e-mail server will accept e-mail to both domains.  Some e-mail severs support domain aliases so the two domains are treated identically, others have to have both addresses on every user.

Secondly, you need to adjust your MX record for the .com domain to point to the correct mail server.  So the MX record points to an A or CNAME record, if there is a CNAME, it will resolve (eventually) to an A record, and the A record points to an IP address.  You can change an MX or CNAME record to point to a different A record or the IP address of the A record can be changed.  Changing the MX record is the simplest option.

The new MX record for the .com domain should look the same as the MX record for the .com.tw domain.

You may also need to reconfigure your users equipment so that they collect mail from the .com.tw server (if not already) and to use the SMTP server that is appropriate too.

These issues are not directly linked to the asked question, but are worth considering anyway.
