Domain A Record
I would like to know if I can share a domain between 2 different hosts, one to manage email and the other to show the actual site.
If I just change the A record of the domain to point to the new IP address where the website sits, would the email sub domain still work with the current host?

The "A" record points to the Web site.
The "MX" record points to the Mail server.
If the "MX" record is missing, the "A" record is used.

Is this what you're looking for:

Your user's mail addresses will work as following:
not as: webmail.domain.tld
The subdomain has nothing to do with the domain where people send mail to, after all, it's the mail server (Dovecot/Postfix) that decides the default host/domain to serve mail on.
To do this, follow my instructions:
1). Your DNS
[webmail.domain.tld]  IN [A] [server ip]
2). Edit /etc/apache2/apache2.conf or /etc/httpd/conf/httpd.conf (path differs depending on your operating system)
3). Restart apache (as sudoer), Note: apache2 is commonly used if you're on Ubuntu or Debian, httpd may be used if on RHEL or CentOS or similar.
Allow from all
service apache2 restart
service httpd restart

Yes you can. You need to edit Zone file. IP address of webserver - A record. IP address of mail server - MX record.
