Ask HN: Modern web mail application to self-host email?
is there any modern webmail client where i can access my own emails that is recent, maintained and has good search functionality (preferably with elasticsearch)?
Saying you want a "self-host" email and then asking for an email client is two different things. Although sometimes they come bundled together, what you are looking for is either an email server or a webmail client or both.
server: Postfix or equivalent (setup to send and receive) client: roundcube, squirrel, etc.
