iRedMail and Dovecot fulltext search

Dovecot, IMAP, iRedMail, Roundcube

I already have quite a large mailbox and I started running into timeout issues when searching in Roundcube mail. AI gave me some instructions for installing the dovecot-fts-xapian plugin, but I kept encountering various errors:

    fts_enforced = yes

    # This one must be 0
    process_limit = 0
}

Eventually, I ended up using Ample, but I ran into memory issues in the browser — during long playback sessions, the browser would start to lag and had trouble handling memory.

In the end, I created my own fork of Ample.fm, where I reworked many parts and resolved the memory issues. Another challenge was having a player for iOS, since background playback via HTML5 doesn’t work very well there — after some time, iOS simply stops the playback. So I also built my own native iOS app that works as a wrapper around Ample.fm.

So my recommendation would be:
