Can send but not receive

[techlists]

Hi,

	I am running Ubuntu 20.04lts / Apache / MySql (or a clone) / PHP / 
BIND9 / Postfix / Dovecot

	Web server works.  I have configred a lot of LAMP virtual host servers. 
 I am new to BIND9 / Postfix / Dovecot.

        FQDN is soho.keiththewebguy.com

	MX record is  :  keiththewebguy.com.     IN MX   10 
soho.keiththewebguy.com.

        A Record : soho.keiththewebguy.com.        IN A    98.191.108.149

	Reverse (PTR) record:  149.108.191.98.in-addr.arpa ->  
soho.keiththewebguy.com

	https://intodns.com/keiththewebguy.com says things are configured 
correctly.

	I have a Let's Encrypt wild card SSL which I placed in Postfix and 
Dovecot.

	Nothing that looks like an error in : /var/log/mail.log or 
/var/log/syslog

        I can send email however I cannot recieve.

        Any thought how I can troubleshoot this?

        Thanks!!
