Post #2358925

I want to store and access my old emails (1 to 20 years old) on-premises, only accessible via the local network (or perhaps VPN). They should be searchable, but read-only, and require no reply or forward support. They'll be accessed infrequently so CPU and ram demands should be minimised between and during accesses. Moving newer mail to this archive will be batched manually. I was originally hoping to find OSS webmail server software with low resource requirements and the option to disable editing. Now I'm considering a read-only IMAP server without SMTP. I considered building my own but I'd get stuck in the weeds around low-mem full text search structures, secure mime and html parsing, and anti-xss dom rendering.
