Mailpit is the (spiritual) successor of mailhog. The mailhog project is dead and has a lot of issues: Issues · mailhog/MailHog · GitHub
Mailpit is more lightweight and supports modern architectures like ARM natively
Hello there 
Thank you for reaching out!
We will forward this to our DevKinsta developers for consideration.
Kind regards
It seems like some interplay between ARM and the macOS Tahoe 26.1 network stack might make this decision for the DevKinsta team:

mailhog has been implicitly unmaintained for five years now, and explicitly for three. mailpit is far-and-away the most widely used alternative.
Thank you for writing back 
I know it’s been a while and this is still in our backlog. I don’t have an ETA yet, but our developers are aware of this and we hope to pick on working on DevKinsta soon.
Thank you
