I tested email from my BBS and while I expected outgoing email to work I was quite suprised when incoming email also works. I had expected I would need to create an MX record in my DNS host in order for other SMTP server to know how to route email back to me.
How does this work? My DNS record for the BBS is daysofoldbbs.wilhartsolutions.com and I checked there is no MX record for this address.

When someone writes an email to you, I think the sending email server just connects to your domain (daysofoldbbs.wilhartsolutions.com) and tries to see if there's an incoming email server running on your domain, and if so, it's able to deliver the email to you.

Modern mail transfer agents (MTAs) will first look to see if there are any MX records associated with the domain name and if there is, attempt to send the mail to one of them (based on the priority field of the MX record). For example, your domain doesn't have an MX record:
$ host digitaldistortionbbs.com
digitaldistortionbbs.com has address 50.39.189.195
But mine has a few MX records:
$ host synchro.net
synchro.net has address 71.95.196.36
synchro.net mail is handled by 0 mail.synchro.net.
synchro.net mail is handled by 2 bbs.synchro.net.
synchro.net mail is handled by 1 cvs.synchro.net.
synchro.net mail is handled by 3 vert.synchro.net.

Interesting, been in IT for 30 years and I can honestly say I have
never tried that. Ican say I always ass-u-med that an MX record was required.
