Yes it is mailbox @ domain not
mailbox @ host. Some mail servers will try to deliver to the A record as a last
resort.

No, what comes after the @ tells the mail server what domain
to look at for the MX record. No short cut just the way SMTP interacts with
DNS.

So this is what
happens when a mail server looks for the MX record of the
doamin
How I am searching:
Searching for
mail.salemradiology.com MX record at i.root-servers.net [192.36.148.17]: Got
referral to J.GTLD-SERVERS.NET. [took 7 ms]
Searching for
mail.salemradiology.com MX record at J.GTLD-SERVERS.NET. [192.48.79.30]: Got
referral to bcw4.bcwebhost.net. [took 196 ms]
Searching for
mail.salemradiology.com MX record at bcw4.bcwebhost.net. [66.224.41.3]: Reports
smtpgw.slmdc.pnwtg.com. [took 116 ms]
Answer:
| Domain | Type | Class | TTL | Answer |
|---|---|---|---|---|
| mail.salemradiology.com. | MX | IN | 43200 | smtpgw.slmdc.pnwtg.com. [Preference = 10] |
| smtpgw.slmdc.pnwtg.com. | A | IN | 68059 | 66.224.124.100 |
Note: the first row in the table, it looks at the domain for the MX record. The domain follows the @ in the email address.
