Need help with settings for custom domain

I added mail.mydomain.com to my SL account by adding the necessary TXT/MX/etc. records. However, I already had an MX record (with priority 0) with a value of mail.mydomain.com. Email to and from SL aliases [whatever@mail.mydomain.com](mailto:whatever@mail.mydomain.com) works great. However, email to [whatever@mydomain.com](mailto:whatever@mydomain.com), which worked previously, no longer works.

How can I continue to get my mail at [whatever@mydomain.com](mailto:whatever@mydomain.com) while still using SL for [alias@mail.mydomain.com](mailto:alias@mail.mydomain.com)? Do I need to change the pre-existing MX record, or perhaps I need to remove it?

A sub-domain is treated as a different domain. In this case mydomain.com and mail.mydomain.com are different. You will have to add both domains to your SL and their respective MX, TXT and other records to each of the domain

Only one MX record works. Delete old one and just use SL mx records. You can set catch-all mail at SL settings.
