Postfix preferred ip
Our suggestion is add an UI element to user area, where end user can change preferred outgoing ip for domain - ipv4 or ipv6. Without mail server config hacks from server admins.
Since Plesk Obsidian 18.0.52, published April 25th, 2023, Plesk sends mail from the domain only via the specific IP address, if a specific IP address version (IPv4 or IPv6) is set for a domain (PPPM-13770).
Please let us know in your comments if this caters your needs or if and what modifications you would like to see.

An option to choose IP for outgoing mail on domain basis.
For now, only below options available:
- all the domains send from particular IP
- each domain uses its IP addressThis feature is for use case when one or several domains can send through one IP address, and the others through another one.
It should be managed independently of web hosting IP address.
