Have you looked into notmuch?

I ended up with installing a dovecot IMAP server that i can connect to from any email client. but no smtp to send emails

Then you connect to the imap server from the email client and search that way

I am also interested in this, my workaround is loading the emails via imap on gmail but i don't really like it

I'd either try loading them into elastic search as a document per email... alternatively, something like mairix or even Thunderbird should do it

for now i've just installed mairix and will search that via ssh, i'll look into all the other suggestions when i have more time, thanks everyone :D

IMAP server like dovecot https://lemmy.world/comment/813653

Access it from thunderbird or a dedicated web interface (still can't find a good one after all these years)
