The messages are quite explicit and and are issued by the REMOTE server.
Recipient address rejected: Access denied
550-Requested action not taken: mailbox unavailable
Youre sending to a server and that server is telling you that the account is not available.

Unless you declare to us what your domain name is we cant help you further troubleshoot is.

However, from a HMS point of view, could you please do a DIAGNOSTIC and post the results here.

My old eyes cant see anything obvious with your DNS records now. However, your MX records are a bit unecessary: you have them pointing to mail.... and smtp.... (separate priorities) which you have both listed under your domain A record (as CNAME) and both point to the same server. Pretty pointless. (Effectively saying: try the server at priority zero first ('smtp...'), and if the server fails to respond, try the same server again (from 'mail...' priority 10).

Reckon you should review your test email that you sent out earlier (asnd bounced as you reported) and maybe try sending to other external addresses too.

Does your DIAGNOSTIC work?

yes you don't need two mx records unless you are using a backup mail server

I would just retain this one

intensifytech.com MX 10 mail.intensifytech.com

and make sure you change your mailhost in hms admin to mail.intensifytech.com and use mail.intensifytech.com in your email clients for smtp,pop and IMAP server name.

but instead of using a cname

mail.intensifytech.com CNAME intensifytech.com

use an A record as follows.

mail.intensifytech.com A 104.187.254.49

delete all references to smtp.intensifytech.com unless you really do have a backup mailserver.
