Why do we use dedicated IP address for email servr or any server- it depends on you how you want to seperate traffic.
You can use WAN exit interface or IP Pool. This depends on how you want to separate traffic.
In this case you may use IP Pool so that emails will use a dedicated IP instead of WAN exit interface IP.
It all depends on you. Technically there are no issues if you use WAN exit interface, or IP Pools.
In the case of 2 ISPs (if you use SDWAN), you use IP Pool, so that your mail server is published with one known external IP, which should be routable
from both ISPs (1 IP for mail server may help in SPF, DKIM,DMARC).
